When you expand n quantities you get n terms for example (a+b) (a+b) gives exactly 4 terms, 2 of of them are like terms which you add them up. Sal has already mastered factoring so he can …

Can't get enough of Sal factoring simple quadratics? Here's a handful of examples just for you! Created by Sal Khan and CK-12 Foundation.

What is factoring? Factoring is the process of breaking down a polynomial into smaller pieces (or "factors") that, when multiplied together, will give you the original polynomial.

What you will learn in this lesson In this article, we will learn how to use a factoring method called grouping.

In practice, you'll rarely be told what type of factoring method (s) to use when encountering a problem. So it's important that you develop some sort of checklist to use to help make the …

Let's do one that traditionally would have been a pretty painful problem if we just tried to do it by factoring, especially if we did it using grouping or something like that.

Factoring out the greatest common factor (GCF) To factor the GCF out of a polynomial, we do the following:

Factoring a polynomial involves writing it as a product of two or more polynomials. It reverses the process of polynomial multiplication. In this article, we'll learn how to factor perfect square …

Factoring, we get: 44 k 5 66 k 4 + 77 k 3 = 11 k 3 (4 k 2) + 11 k 3 (6 k) + 11 k 3 (7) = 11 k 3 (4 k 2 6 k + 7)

Factoring it out preserves the equation whilst dividing the equation by, for example it's GCF, removes that aspect of the equation. As a result from that, there might be some loss of …
