Answer:
x=4 and x=-4
Step-by-step explanation:
you dont really have to solve this one when you multiply the answer choices they should equal your B which is -16 and only 4 • -4 = -16 so yeah thats your answer
First simplify
(x^2+2x+1)-4
x^2+2x-3
Then factor
(x+3)(x-1)=x^2+2x-3
I solved your other quesiton too.
