Use this for formula

firstly

ax²+bx+c=0

and then

b±√(b²-4ac))/(2a)

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]
