Stuck? Use a hint.

1.1 Factoring x2+4x-32

The first term is, x2 its coefficient is 1 .

The middle term is, +4x its coefficient is 4 .

The last term, "the constant", is -32

Step-1 : Multiply the coefficient of the first term by the constant 1 • -32 = -32

Step-2 : Find two factors of -32 whose sum equals the coefficient of the middle term, which is 4 .

-32 + 1 = -31

-16 + 2 = -14

-8 + 4 = -4

-4 + 8 = 4
