You can put this solution on YOUR website!
w for width and L for length give area A according to wL=A.

You have an expression for area and an expression for one of the dimensions, and you want to know the other dimension.

x%5E2%2Bx-30=b%2A%28x%2B6%29, using b as your other unknown expression for that dimension.

Can you factorize the area expression? Any common factor in both the left member and the right member?
