second case is irrelevant since both sides are positive, so you are free to square them and solve the quadratic inequality, provided of course that we require

Thanks Krizalid .
So i will only need to solve to get my solution right ?
that's because you need to restrict the square root.
solution set for the quadratic inequality is but this is not the full solution, 'cause on the other hand we require thus the solution set it's actually which is our full solution set.
