In this tutorial the instructor shows how to factor a trinomial with Greatest Common Factor (GCF) and then how to group it. The first thing you have to do when you want to factor a trinomial is look for the GCF. First factor the numerical coefficients of the terms of the equation. Now separate out the common numerical factor and if any common variable. This leaves you with a binomial to be factored. Now to solve this multiply the numerical coefficients of the first term and the last term and ...
In this video, you will learn how to factor a simple trinomial. You will learn how to recognize a simple trinomial, and how to completely factor the trinomial. Also, it shows you how to factor square variables. The last example in the video explains how to factor out a negative first term. You can't just drop the negative and forget it is there. The instructor teaches you how to remove this negative, then reminds you not to forget to put the negative into your final answer.
Just because fixed rate mortgage rates have dropped to historic lows doesn't mean that you should automatically refinance. With the economic climate you might not be able to refinance because many banks have tightened the rules for refinancing. As for who is eligible, you will need a 700-720 on your credit score to get the best rates. To refinance at all you need at least a 600. Generally it is worthwhile to refinance if you can save at least a half point off of your current rate. But you do ...

In this video the instructor shows how to find the slope of an equation which is in the form Ax + By + C = 0. He says that the formula to find the slope of a line in the above form is slope m = -A/B, where A and B are the numeric constants of the variables x and y in the given equation. He goes on and further shows how to do this with a couple of examples. He shows how to reduce any equation into the general form and how to apply the slope formula then. This video shows how to find the slope ...
Central limit theorum is easily one of the most fundamental and profound concepts in statistics and perhaps in mathematics as a whole. In probability theory, the central limit theorum (CLT) states conditions under which the mean of a suffiently large number of independent random large variables (each with finite means and variance) will be normally distributed, approximately. Huh? If you are having trouble understanding central limit theorum and need help trying to solve it, check out this tu...

Did you know that almost 85 percent of women wear the wrong bra size? Wearing the wrong size can cause sagging, discomfort and stress on your back. The right bra can be flattering to your outfit, comfortable and fitting and make you feel more confident about yourself. A bra size is composed of two measurements: your band size and your cup size. The band size is important and the bra needs to fit snugly around you, not too tight but not loose. The cup size is important to prevent breast damage...
By using almost any packet-crafting tool, a hacker can perform denial-of-service (DoS) attacks. With the power to create just about any packet with any characteristics, a hacker can easily find one that will take down a host or network. Nmap and Hping are effective packet manipulation tools, but there's also Scapy, which is almost infinitely customizable.
When the Nintendo 3DS XL came out, I traded in my regular sized Nintendo 3DS for one — but I ended up hating it. The XL just felt big and unwieldy, and because the screens were larger (with the same resolution), it ended up looking blurrier than the regular 3DS. This, to a less severe extent, is the argument for the Galaxy S9 against the Note 8.
An incorrectly scaled object in your HoloLens app can make or break your project, so it's important to get scaling in Unity down, such as working with uniform and non-uniform factors, before moving onto to other aspects of your app.
While attempting to hack a web app, there may come a point where the attacker may have to escape the default directory in order to access unauthorized files. This is known as a directory traversal attack. Much as the name implies, this attack involved traversing the servers directories. But in order to move to an unauthorized directory, we need to know where those directories are. Today we'll be building a tool to brute force these directory locations based on HTTP response codes. Before we g...

In this how to video, you will learn how to re-size an image for printing using Photoshop. First, open the image you want to re-size in the program. Next, go to image and select image size. From here, you will see the current size of the image. You can change the units of the sizing. The resolution is the number of dots printed per inch. De-select re-sample to change the resolution of the image only when printing. 300 is the standard resolution. When you re-size the image, make sure constrain...
In this video, the instructor shows how to collect like terms and factorize. When you are given a linear equation, the first thing you do is to try to organize it. Pair up the like terms. Add the numerical coefficients of terms with the same variables. This is called collecting the like terms. In case you see any common factor across all the terms, pull it out and tag it to the parenthesis. In this way, you can factorize the equation. Next, bunch together your like terms and sum them up. The ...

Hi I am a new member of null byte(although I am reading this website from the beginning) and this is going to be my first post.
Well, first things firsts, it's been awhile! I'm sorry the series has been dead for a little bit, but I recently hit some personal relationship issues and needed to take some time to think. But, now that it's all said and done, the dust can settle and we can start training again!
In the last iteration of how to train your python, we covered basic string manipulation and how we can use it to better evaluate user input. So, today we'll be covering how to take user input. User input is very important to scripting. How can we do what the user says if we can't tell what the user wants? There are multiple ways to take input, we can give the user a prompt and take input from them directly, or we could use flags/switches, and take their input before the script is even execute...
Hi there, Crackers, Welcome to my 7th post (Part-1), this tutorial will explain about the basics of Batch Scripting.
There is many different types of stars in the universe. Majority of them are red dwarf stars. However, there are plenty of stars like ordinary stars (like our sun), red giants, blue stars and etc. Furthermore, when you look in the night sky, we see a lot of small and bright stars. What people don't know is that there are stars that are not even completely understood by astronomers and scientists.
I am not a morning person. This is a fact that has been proven with science. I need every bit of help to get me out of bed in the morning—multiple alarms, extremely loud tones, Pandora—I've tried everything.
While still extremely awesome, the Samsung Galaxy Gear smartwatch is limited as to what you can download on to it, especially apps. It also doesn't have its own internet access (only Bluetooth), so apps like Instagram, Facebook, and Vine have yet to make their way to the Gear Store.
