What is the factored form of this expression? x2 + 6x - 16

(x + 2) (x - 8)

Step-by-step explanation:

I did this by using the AC method. The AC method of factoring is basically a method to split the middle term bx into 2 separate terms so that you can eventually factor the trinomial using grouping. In order to split the middle term we will need to find the factors that make up the product of the coefficient A and C

(x-2) (x+8)
