I hope the given equation is :


√(x+2) -15 =-3

First step to solve the above equation is to add 15 to each sides of the equation. Therefore,


√(x+2) -15+15 =-3+15


√(x+2) =12

Next step is to remove square root from the left side, so let's square on each sides of the equation. So,

x + 2= 12²

x + 2 = 144

x = 144 - 2

So, x = 142

So, a is the correct choice.

Hope this helps you!
