Question

Please help ;.; the second step in factoring the trinomial x^2-4x-32
a.list all the factors of the 4
b.list all the factors of 32
c.find the sum of the factors of 32
d.find the sum of the factors of 4

Answer 1

8x4
32x1
1x4
2x2

Answer 2

yesx^2-12x+32

factoring will result in 2 products:

(x - ?)(x - ) Asking ourselves what 2 numbers have a product of 32 and sum of 12?

We NEED the 'sum of the inner and outer products' to match that middle term -12x.

(x - 8)(x - 4) Using 4 and 8 works as:

SUM of the outer product(-4x) and the inner product(-8x) = -12x from algebra.com

nope, it was c...
