Use the discriminant to determine the number and type of solutions for the equation 2x^2−4x+7=0 (A). The equation has 2 real solutions because the discriminant is positive.
(B). The equation has 1 real solution and 1 imaginary solution because the discriminant is negative.
(C). The equation has 2 imaginary solutions because the discriminant is negative.
(D). The equation has 1 real solution because the discriminant is 0.
