im trying to rearrange the following equation for x but getting confused because of the brackets and squares. I understand the process of changing the subject but on more simple equations. Please can you help me. Here's the equation
y = 3(x+5)^2

divide by three.
y/3=(x+5)^2
take the square root of each side.
+sqrt(y/3)=x+5
solve for x. check both roots.
