Question #6d4f8

Answer 1

You get `(a-2)(a+1)`

Explanation:

We need two numbers to multiply to -2, and to add up to -1. Through trial and error, we can find out that these two numbers are -2 and 1.

`-2xx1=-2`
`-2+1=-1`

Since `a` does not have a coefficient, in the answer it will just remain as `a`.

Using -2 and 1 we get:

`(a-2)(a+1)`
