Answer:

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)#
