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.
