Question

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

Answer 1

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}}}\\`

Answer 2

Use this for formula

firstly

ax²+bx+c=0

and then

b±√(b²-4ac))/(2a)
