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 :)
