Hi I cant seem to factorize x^2-2x-1
I need to arrange it so it can be multiplied out ( )( )
Help please?
Use the quadratic formula: $\displaystyle x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$. Find two values of x, and then write them in the form ($\displaystyle x-\alpha)(x-\beta)$, where $\displaystyle \alpha$ and $\displaystyle \beta$ are the two solutions of the equation.
