1 . step
First compare the given equation with
general form
[tex]{a{x}^{2}\:+\:bx\:+\:c\:=\:0}[/tex]
2. step
Then find the value of discriminant
by the given equation below
[tex]\mapsto{{b}^{2}\:-\:4ac}[/tex]
3. step
subsitute the value of discriminant and other given value in Quadratic formula as per the equation .
[tex]{\rightarrow{\frac{-\:b\:±\:\sqrt{{b}^{2}\:-\:4ac}}{2a}}}\\[/tex]
