Answer:

x = 0

Explanation:

First, multiply the -3 by two (-3(x + 2)2 + 4 = -8) -- -6(x+2)+4 = -8.

Then, subtract 4 from both sides (-6(x+2)+4 = -8) -- -6(x+2) = -12

After that, divide both sides by -6 (-6(x+2) = -8) --
(-6\left(x+2\right))/(-6)=(-12)/(-6)

Simplify -- x+2=2

Subtract 2 from both sides (x+2=2) -- x = 0

Hope this helped! Good luck with future math problems :)

X=0

-3(0+2)2+4 distribute -3 to the parentheses-PEMDAS
(0-6)2+4 multiply 2 by the parentheses
(0-12)+4 solve the equation
= -8
