Answer:

x= 2 and x= -6

Step-by-step explanation:

3(x+2)^2=48

1)   [3(x+2)^2]/3=48/3

2) (x+2)^2 = 16

3) √(x+2)^2 =+/-√16

4) x+2 = 4   and    x+2 = -4

5) x=2          and   x= - 6

Check:

3(x+2)^2=48

3(2+2)^2 = 48           and        3(-6+2)^2=48

48 = 48                                   48=48
