Question

What is the discriminant of the quadratic equation 3 – 4x = –6x2?

–68
–56
76
88

Answer 1

The answer would be: -56

Answer 2

`D = -56`.

Explanation:

Given : -6x² = 3 -4x.

To find : What is the discriminant of the quadratic equation .

Solution : We have given that -6x² = 3 -4x.

Rewrite the equation : -6x²+ 4x -3 = 0.

Standard form of quadratic form : ax²+ bx + c = 0.

Discriminant =
`D = b^(2)-4ac`.

Then, a = -6 , b =4 , c =-3

`D = 4^(2)-4(-6)(-3)`.

`D = 16 - 72`.

`D = -56`.

Therefore,
`D = -56`.
