quite simple actually, i struggles on one of these, see how it resembles x²-6x+2?

factorise it.

instead of x² it's x
and instead of 6x it's remember that

Try substituting y = x1/2 into the equation, and then solve the quadratic - then substitute back to get your answers
9. Make the substitution and solve for y then for x.

It's a disguised quadratic.

Edit: ^^ it appears others have got there first.
10. it is a "disguised quadratic"

12. Or you could just square the whole equation and solve it like a normal quadratic equation.

Edit: This is wrong
