Question

What is the value of the discriminant for the quadratic equation 0 = 2x2 + x – 3?

Discriminant = b2 – 4ac

Answer 1

25

I seen it already

Answer 2

This is called standered form:

`ax^2+bx+c=0`

This formula will guide you to the values of a, b, and c needed to find the discriminant

We are given:
0 = 2x^2 + x – 3

Ignore the 0=
2x^2 + x – 3

a=2

b=1
c=-3

Plug them into the discriminant :

`b^2 - 4ac`


`(1)^2 - 4(2)(-3)=25`

Final answer: 25
