\[2x^2  5x + 5 = 0\]multiply by \(1\) to make life nicer get \[2x^2 + 5x  5 = 0\]use \[x=\frac{b\pm\sqrt{b^24ac}}{2a}\] with \[a=2,b=5,c=5\]

put the numbers in the slot,s, do the arithmetic carefully \[x=\frac{(5)\pm\sqrt{(5)^24\times 1\times 5}}{2\times 2}\]

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