We need to factor this we need it to look like this \[\huge~\rm~ax^2+bx+c=0\]
how would we make it look like that ^
test the discriminant \(\large\color{black}{ \displaystyle x^2 + 15x +56=0}\) \(\large\color{black}{ \displaystyle {\rm Discriminant} = \sqrt{15^2-4\cdot1\cdot56}}\) \(\large\color{black}{ \displaystyle {\rm Discriminant} = \sqrt{225-224}=1}\)
