How do you factor a quadratic expression?

If you've gotten this far, the quadratic expression must be of the form ax^2+bx+c ax2 +bx +c where a eq 1 a = 1. If there are factors of ac ac that add up to b b, factor using the grouping method. If not, the quadratic expression cannot be factored further.

What if a polynomial shares a common factor?

If each term in the polynomial shares a common factor. . . If the first and last terms are perfect squares and the middle term is twice the product of their square roots. If the expression represents a difference of squares. In practice, you'll rarely be told what type of factoring method (s) to use when encountering a problem.
