Question

Using complete sentences, explain how to completely factor 2x2 − 6x − 36.

Answer 1

(2x+6)(x-6)

Answer 2

There will definitely be a 2x and an x at the beginning of the two brackets to give the 2x2.
the ends in both the brackets must multiply to give -36.
you have 6 and -6, 18 and-2, -2 and 18, 36 and -1, -36 and 1.
then its just a case of trial and improvement to figure out which pair are adequate..

Answer 3
