1. Why is 8x² + 16x = 4x (2x + 4) true yet not factored correctly?

2. The lead term of a polynomial is -2x³ and you are told to GCF factor. Without knowing the rest of the polynomial what can be factored out?

3. Factor 2x³ + 14x²+ 24x completely.

4. You are told to factor x² + ax + b. If a is negative and b positive which of the following forms would the factorization have to have? Why?

(x - )( x - ) (x + )(x + ) ( x + )(x - )
