Question

What is the value of the discriminant for the quadratic equation

Answer 1

To find the discriminant, we can use this formula:

b^2 - 4ac

Our quadratic is:

2x^2 + x - 3

Let's plug in our values.

(1)^2 - 4(2)(-3)

Simplify.

1 - (-24)

1 + 24

25

The value of the discriminant is 25.

The correct answer is C.
