Solving quadratic equations

Solve the equation x-6x^0.5+2=0, giving your answers in the form p +/- q root r, where p, q and r are integers.

Is it one of those questions where you say let x^1/2 be y so it would be y^2 - 6y + 2=0? If yes I solved it and can’t manage to get it in that form.

Post your working 🙂 Just trying it in my head and it looks like it's going to drop out OK, but I could be wrong!
