This video shows the method to add rational expressions with different denominators. The first step in this process involves finding the LCD. After this is done, the numerator and denominator are multiplied by a specific number so that the fractions are rewritten with common denominators. In the second step the numerators are added or subtracted according to the problem with LCD in the denominator. Simplify the numerator by adding or subtracting like terms. After this, we get a rational expre...
The video describes the basic process of multiplying two rational expressions. The problem illustrated in this video involved multiplying rational expressions of monomial terms with integer coefficients. As with the other example problems, we follow the steps of: factoring, canceling, and multiplying. Because these terms are monomials, no factoring is required (but we still state it as a step for similarity to solving other problems). We then find the greatest common divisor for both terms to...
One can learn, from watching this video, how to multiply and divide fractions. Prof. Alexander gives a discourse on multiplication and division of fractions in a simple, easy way. For multiplication, one should first look for highest common factor in the numerator of one fraction and the denominator of the other, and vice versa, and if found, carry out the reduction by that factor. Then the numerator of one fraction is multiplied by that of the other fraction, the same operation is carried ou...
This video will show you how to carry out multiplication of fractions using cancellation, which will make your fraction multiplication problems simpler to solve. You will need to look at the numerator of the first fraction and the denominator of the second fraction and see if you can find a common factor between the two numbers. If one does exist, you can simply divide both numbers by that common factor and simplify. Repeat this for the other numerator and denominator and if possible, your fr...
This video teaches you how to use APT (Arbitrage Pricing Theory) models and formulas.

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 ...
