Best ResponseYou've already chosen the best response.0\(\bf \textit{quadratic formula}\\ {\color{blue}{ 1}}z^2{\color{red}{ 2}}z{\color{green}{ +5}}=0 \qquad \qquad z= \cfrac{  {\color{red}{ b}} \pm \sqrt { {\color{red}{ b}}^2 4{\color{blue}{ a}}{\color{green}{ c}}}}{2{\color{blue}{ a}}}\) what does that give you?
