if you want to eliminate the square roots, you have to square both sides of your equation. Make sure you use the binomial formula correctly and be aware that the transformation of the equation doesnotgive an equivalent equation:

LHS of equation:

RHS of equation:

Square both sides again:

LHS of equation: 144

RHS of equation:

Isolate the square root on one side of your equation:

Divide first by 8 and then square both sides of your equation. Use with your RHS!

After a whole bunch of transformation you'll get:

To solve this equation is certainly no problem for you.

You have to prove whether your solution fits into the original equation or not, because you have made often no equavelant transformation!
