Question

How do i factor
x^2+4x-12?

Answer 1

Note:

-6 * 2 = -12.

Try using that to solve.

Answer 2

That didn't help at all

Answer 3

well i would start with finding the factors of 12

Answer 4

would it be (4x-6)(4x+2)?

Answer 5

Do the 4's cancel out?

Answer 6

The form that you are looking for is:

(x + a) ( x - b)

Where a * b = -12 and a + 6 = +4

So,

(x + 6) (x - 2) = x^2 + 4x - 12

Answer 7

after looking at the factors
1,12
2,6
3,4
find which one subtracted from the other equals the middle term 4
