Factoring quadratic trinomials in the form (ax 2 + bx +

c. where a = ≠ 1

You can try the ac method.

1. Try to factor a common factor from all terms.

2. Multiply ac.

3. Find two factors of ac that add to b, call them p and q.

4. Rewrite the trinomial with the bx term broken up into into px + qx.

5. Factor by grouping.
