Complete Question:

Which statement about the following equation is true?

A) The discriminant is less than 0, so there are two real roots

B) The discriminant is less than 0, so there are two complex roots

C) The discriminant is greater than 0, so there are two real roots

D) The discriminant is greater than 0, so there are two complex roots

C) The discriminant is greater than 0, so there are two real roots

Step-by-step explanation:

The given equation is which by simplification becomes

For a quadratic equation of the form , the discriminant is given by the equation,

If the discriminant D is greater than 0, the roots are real and different

If the discriminant D is equal to 0, the roots are real and equal

If the discriminant D is less than 0, the roots are imaginary

For the quadratic equation under consideration, a = 2, b = -9, c = 3

Let us calculate the discriminant D

D = (-9)² - 4(2)(3)

D = 81 - 24

D = 57

Since the Discriminant D is greater than 0, the roots are real and different.

not sure but it may be b, as i said i'm not sure.
