The discriminant is the formula . So, where do the a,b, and c come from? It comes from quadratic equation once it's already in the form .

Your equation is already in the correct form, so you can readily pull out the a, b, and c. For this one, the a = -4, b = 3, and c = -28. We'll plug those into the discriminant formula and see what kind of value we'll get:

The discriminant turned out to be a negative number. This means that your quadratic equation has no real number solutions.

IF , quadratic equation has NO SOLUTION.
IF , quadratic equation has EXACTLY 1 SOLUTION.
IF , quadratic equation has EXACTLY 2 SOLUTIONS.
