This is a very interesting mathematical instructional video on how to find rational equation with no solution. How to solve the equation and check the answer. Let us take the example m over m-3 minus 4 is equal to 3 over m-3. In this equation we get m-4m+12 over m-3 is equal to 3 over m-3. When we simplify it further we get -3m +12 = 3. Or -3m = -9 and m = 3. This video teaches you very clearly how to solve a rational equation with no solution.
In this video the instructor shows how to divide rational expressions that contain trinomials.

The method the video teaches is to find the prime factors of both numerator and the denominator to simplify the ...
Watch this video to learn how to multiply fractions by fractions. First multiply the top numbers together. For example, if you have 3/5 * 4/7, multiply 3 * 4 and put your product on top of the fraction you will get as a product. Next, multiply the bottom numbers together and put them on the bottom of your resulting fraction. Next see if you can reduce your product to simplify it. You could also do the reducing step first by canceling out any common factors in the numerators and denominators o...

This video gives a simple two step method on how to solve ratios and proportions.
To find the length of a side of a triangle using cosine, you first need to find the angle and which sides are given. After you determine the angle and given sides, you'll need to figure out which trigonometric ratio to use. If you are given the adjacent side and the hypotenuse, you need to use cosine to solve. The degree equals adjacent divided by hypotenuse. In the example, Cos 39=3.5/x. After simplifying the equation, we found x to be 4.49. If the directions ask you to round, be sure to rou...
This video will show you how to carry out multiplication of fractions using cancellation, which will make your fraction multiplication problems simpler to solve.
