3. X-BOX factoring
This is a guaranteed method for factoring quadratic equations – no guessing necessary!
Background Knowledge needed:
Dividing a polynomial by a monomial using the box method (we did this last lesson)

4. Factor the X-Box Way 2x 4x x 2 4 6 8 2 4 Answer: (x + 2) (x + 4)
Example: factor 2x 4x x 2 4
(1)(8)= 6 8 2 4
Answer: (x + 2) (x + 4)
