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

So firstly, using our equation plug in the values into the discriminant formula and solve as such:

(-7)² - 4 × 3 × 4

49 - 48

1

So our discriminant is 1. Since 1 is positive and a perfect square, this means that there are 2 real, rational solutions.
