Ответ:
x = 0
Step-by-step 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) --![\frac{-6\left(x+2\right)}{-6}=\frac{-12}{-6}](/tpl/images/0646/1178/cc196.png)
Simplify -- x+2=2
Subtract 2 from both sides (x+2=2) -- x = 0
Hope this helped! Good luck with future math problems :)
