$\displaystyle

x^3 - 2x^2 + 1 =0

$

I've tried using the quadratic formula but the only solution I am getting for x is 1. It is supposed to have solutions of approximately x=-0.62 and x=1.62 also, but where do you get these answers.

Anyway, if anyone could show complete working out to see how I didn't get these solutions it will be appreciated!
