Type II — the root larger than an expression

Second canonical type: the root must be larger than an expression without a radical, $\sqrt{A(x)}\ge B(x)$. Here the right-hand side may have any sign, and the solution arises from the union of two cases: the one in which $B(x)$ is negative (inequality automatically true) and the one in which it is non-negative (we square).
