WebQuestion: how mant real roots does a quadratic equation have if the discriminant is 10. how mant real roots does a quadratic equation have if the discriminant is 10. Expert Answer. Who are the experts? Experts are tested by Chegg as specialists in their subject area. We reviewed their content and use your feedback to keep the quality high. WebQuadratic functions may have zero, one or two roots. An easy example is the following: f (x) = x^2 - 1 When setting x^2-1 = 0, we see that x^2 = 1. This is the case for both x = 1 and x = -1. An example of a quadratic function with only one root is the function x^2. This is only equal to zero when x is equal to zero.
