Question

Please help with this

Answer 1

`3(x+2)^2=48\qquad\boxed{\text{divide both sides by 3}}\\\\(x+2)^2=16\qquad\boxed{\text{take the square root of both sides}}\\\\√((x+2)^2)=√(16)\\\\|x+2|=4\iff x+2=-4\ \vee\ x+2=4\qquad\boxed{\text{subtract 2 from both sides}}\\\\x=-6\ \vee\ x=2`

Answer 2

Divide both side by 3

take the square root of both sides

subtract 2 from both side
