Question

What is the other solution??

Answer 1

Answer:

x = 12

Step-by-step explanation:

Just because one  of the solution is x=-2 it means that we have something like this (x + 2)*(some statement here), if we divide above mentioned statement to (x + 2) we will get x - 12, so initial multiplication is (x + 2)(x - 12) which leads to another answer x = 12

Answer 2

Answer:

The other solution is 12.

Step-by-step explanation:

Break the solution into groups: (x^2+2x)+(-12x-24)

Factor out the x^2 from the first group to get x(x+2)

Factor out the -12 out of the second group to get -12(x-12)

Here we get (x-12)(x+2)

You can see solutions are -2 and 12.
