Anderson uses the discriminant to correctly find the number of real solutions of the quadratic equation x2 + 4x + 8 = 0. Which explanation could Anderson provide?
a. The equation has no real number solutions because the discriminant is 0.
b. The equation has one real number solution because the discriminant is 0.
c. The equation has no real number solutions because the discriminant is less than 0.
d. The equation has two real number solutions because the discriminant is greater than 0.
