More Factoring - 1

Sometimes you can combine two or more terms at a time in such a way that each term has an algebraic expression as a common factor.

Examples

3x2 – 3 + x3 – x

If 3 is factored from the first two terms and x is factored from the last two terms, we would have two terms with a factor of x2 – 1.

3x2 – 3 + x3 – x = 3(x2 – 1) + x(x2 – 1) = (3 + x)(x2 – 1)

You could also combine the first and third terms and the second and fourth terms.
