Question

What is the discriminant of the quadratic equation 3 – 4x = –6x2? –68 –56 76 88

Answer 1

the discriminant of the quadratic equation is -56 y-step explanation:

Answer 2

we know that

The discriminant of the quadratic equation of the form

`ax^(2) +bx+c=0`

is equal to
`(b^(2)-4ac )`

we have

`3 -4x = -6x^(2)`

`3 -4x = -6x^(2) \\ -6x^(2)+4x-3=0`

in this problem

`a=-6\\ b=4\\ c=-3`

Substitute in the formula of discriminant

`(b^(2)-4ac )=4^(2)-4*(-6)*(-3)\\ =16-4*18\\ =-56`

therefore

the answer is

the discriminant of the quadratic equation is
`-56`
