A quadratic equation has a discriminant of 12. Which could be the equation?

For a quadratic equation ax² + bx + c = 0, the discriminant is b² − 4ac. In choice B, a = 2, b = 6, and c = 3, so the discriminant is 6² − 4(2)(3) = 36 − 24 = 12. Therefore, the equation 0 = 2x² + 6x + 3 could have a discriminant of 12.
