Question

Mattie uses the discriminant to determine the number of zeros the quadratic equation 0 = 3x2 – 7x + 4 has. Which best describes the discriminant and the number of zeros?

Answer 1

Answer:  2 real zeros

discriminant:  b^2 - 4ac
a = 3, b = -7, and c = 4
so, (-7)^2 - 4(3)(4) = 1
Since the discriminant is positive, there are 2 real zeros, if the discriminant was negative there would be 2 complex zeros, and if the discriminant equaled 0 then there is one real answer

Answer 2

Answer:

2 zeros

Step-by-step explanation:

the discriminant is positive
