    2. \frac{2}{y}=\frac{3}{y^2}+2 Mr F says: \therefore 2y = 3 + 2y^2 \therefore 2y^2 - 2y + 3 = 0, which has no real solutions.

    3. \sqrt3x^2=8\sqrt2x-4\sqrt3 Mr F says: \therefore 3x^2 = 8\sqrt{6}x - 12 \therefore 3x^2 - 8\sqrt{6} x + 12 = 0, solved in several ways eg. by using the quadratic formula.
