How to simplify g(x) = -2(x-1)(x+5)

x=1 and x=-5

Step-by-step explanation:

To finally get the answer we will set everything equal to 0 so we will get

-2 = 0

This is an extraneous solution aka an answer that just doesn't make sense so we disregard the answer. This is really only useful to do if there is an x on the outside of the parenthesis.

x-1 = 0

add 1 on both sides

x-1

x+5=0

subtract 5 on both sides

x=-5
