Greatest Common Factors - Problem 6 630 views
Factoring is the process of taking a polynomial that is a string of sums and differences and re-writing the expression as a product. This is a complicated process, but the first step is always looking for and "undistributing" a greatest common factor if one exists. In these problems, we are looking for what number or letters multiplies into all terms of the polynomial. Don't forget that the exponents are added when we write things as products like this. Lastly, sometimes it is useful to pull out a negative factor, even though it would technically not be the greatest factor.
