Question

The discriminant of a quadratic equation is the value b^2-4ac what is the value of discriminant of 0=-2x^2+6x+13

Answer 1

-16

Explanation:

Given data

We are given the expression

0=-2x^2+6x+13

a=-1

b=6

c=13

The discriminant of a quadratic equation is the value b^2-4ac

Substitute

=6^2-4(-1*13)

=36-4(13)

=36-52

=-16

Hence the discriminant is -16
