Watch Video on Factoring by Grouping – Algebra Help
Access full lesson containing this video at: http://www.yourteacher.com/algebra2/factoringbygrouping.php Students learn to factor a polynomial that has four terms by grouping the first two terms together and the last two terms together, then factoring out the Greatest Common Factor from each group. For example, to factor ax — ay + cx — cy, the first step is to factor out an “a” from the first two terms, and factor out a “c” from the last two terms, to get a(x — y) + c(x — y). The problem can now be thought of as two terms, each with a Greatest Common Factor of (x — y), so an (x — y) can be factored out, to get (x — y)(a + c).

exponent rules, …
exponent rules, when you divide exponents, you substract the bottom exponent from the top exponent X3/x (x is that GFC) x3-x equals x2

it’s x^2 because x^ …
it’s x^2 because x^2 (x-2) gets you x^3 – 2x^2
x^2 can go into both x^3 and -2x^2
x can also go into both x^3 and -2x^2. you would get the answer as: x (x^2-2x). however, they don’t want this answer, they want the one with the greatest common factor, which is x^2. it’s x^2 and not x because x^2 is greater.
hope that helped…
