(x+2)²=3(x+2)

for the (x+2)² , just do this one (x+2)(x+2)  distribute the X the answer is                                                x²+2x+2x+4 is x²+4x+4
for the 3(x+2)² , first is is the number inside the parenthesis the (x+2)(x+2)  distribute the X the answer is                     x²+4x+4

3(x²+4x+4) distribute 3x²+12x+12 

Solve : 

x²+4x+4 =3x²+12x+12
3x²+12x+12-x²-4x-4
2x²+8x+8=0 is the standard form
