What is the value of the discriminant for the quadratic equation 0 = 2x^2 + x - 3?

Discriminant = b^2 - 4ac

A) - 25

B) - 23

C) 25

D) 26

What is the value of the discriminant for the quadratic equation 0 = 2x^2 + x - 3?

It would be C 25

The discriminant tells or discriminates how many roots there will be and what kind they are

that is the bit under the square root sign with is b^2-4ac

when you have

ax^2+bx+c=0

we have

2x^2+1x-3=0

a=2

b=1

c=-3

sub

b^2-4ac

1^2-4*2*-3

1+24

25

the discriminant is 25 C
