Question

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

Discriminant = b^2-4ac

A.-25

B.-23

C.25

D.26

Answer 1

Answer: 25

Step-by-step explanation: The quadratic equation may be expressed in a form, ax² + bx + c =0. From the given equation, a = 2, b = 1, and c = -3. Substituting these value to the equation of the discriminant (D).

                                       D = b² - 4ac

                                   D = 1² - (4)(2)(-3) = 25

Thus, the discriminant of the equation of 25.
