\[-2x^2 - 5x + 5 = 0\]multiply by \(-1\) to make life nicer get \[2x^2 + 5x - 5 = 0\]use \[x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\] with \[a=2,b=-5,c=5\]

put the numbers in the slot,s, do the arithmetic carefully \[x=\frac{-(-5)\pm\sqrt{(-5)^2-4\times 1\times 5}}{2\times 2}\]

\[\implies x = \frac{-(-5) ± \sqrt{(-5)^2 - 4(-2)(5)}}{2(-2)}\]\[ \implies x = \frac{5 ± \sqrt{25 + 40}}{-4}\]\[\implies x = -\frac{5 ± \sqrt{65}}{4}\]\[\implies x = -\frac54 ± \frac{\sqrt{65}}{4}\]Do you see how I got that based on my first post?
