see below

Explanation:

well first you have to get rid of 3 which you would divide on both sides. and now to counter ^2, you have to square root on both sides. then you can just subtract 4 from both sides and you have your answer

x= -1 , -7

Explanation:

3(x+4)^2 = 27
3(x^2+8x+ 16) = 27
x^2+8x+16=9
x^2 +8x= 9-16
x^2+8x=-7

Quadratic Equation
x^2+8x+7=0
x^2+7x+x+7=0
x(x+7)+1(x+7)= 0
(x+1) (x+7)=0
x= -1 , x=-7

Hope it Helps
Cheers :)
