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

  • maths -

    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.
