Question

how do you use quadratic functions?
and please get correct!

Answer 1

Use this for formula

firstly

ax²+bx+c=0

and then

b±√(b²-4ac))/(2a)

Answer 2

1 . step

First compare the given equation with

general form

${a{x}^{2}\:+\:bx\:+\:c\:=\:0}$

2. step

Then find the value of discriminant

by the given equation below

$\mapsto{{b}^{2}\:-\:4ac}$

3. step

subsitute the value of discriminant and other given value in Quadratic formula as per the equation .

${\rightarrow{\frac{-\:b\:±\:\sqrt{{b}^{2}\:-\:4ac}}{2a}}}$
