**(x + 4)(x + 7) = x2 + 11x + 28 (x + 14)(x + 2) = x2 + 16x + 28**

Find the product. (x + 4)(x + 7) (x + 14)(x + 2) = x2 + 11x + 28 = x2 + 16x + 28 Factor. 3. 10x + 25 4. 28x2 + 35x 5. x3 + 2x2 + 4x + 8 = 5(2x + 5) = 7x(4x + 5) = (x2 + 4) (x + 2)

**Sign Rule: When the last term is POSITIVE…**

The signs inside the parenthesis will be the SAME as the middle number’s sign

3
**Figuring out the Numbers**

Check to see… What factors to give you the last number AND adds to give you the middle number?
