Best ResponseYou've already chosen the best response.1\[\large\rm \color{green}{1}x^2+\color{orangered}{9}x+\color{royalblue}{10}=0\]And our formula is,\[\large\rm x=\frac{\color{orangered}{b}\pm\sqrt{\color{orangered}{b}^24\color{green}{a}\color{royalblue}{c}}}{2\color{green}{a}}\]ya? :o Understand why I put a 1 on the x^2?
