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
