Quadratic formula \[x=b \pm \sqrt{b^24ac}/2a\]

nubeer Group TitleBest ResponseYou've already chosen the best response.0
\[x = \frac{ b \pm \sqrt{b ^{2}4ac } }{ 2a}\] this is the quadratic formula now look at your equation it's x^29x+20 so a =1 ,b = 9 , c = 20 just plug in values you will get 2 values of x
