Question

The discriminant of the quadratic equation is
(a)D=0
(b)D=b2-4ac
(c)D=b2+4ac
(d)D=b/4ac​

Answer 1

Answer:

b. b^2 - 4ac is the answer

Answer 2

Answer:

The discriminant is the expression b2 - 4ac, which is defined for any quadratic equation ax2 + bx + c = 0. Based upon the sign of the expression, you can determine how many real number solutions the quadratic equation has. ... If you get a negative number, the quadratic will have no real solutions, just two imaginary ones.
