Learn how to solve discriminant of quadratic equation problems step by step online. Find the discriminant of the equation -2x^2+12x+5=0. The discriminant (D) of a quadratic polynomial of the form ax^2+bx+c is calculated using the following formula, where a, b and c are the coefficients of the corresponding terms. From the equation, we see that a=-2, b=12 and c=5. Replacing the values of a, b and c in the previous formula, we obtain. Multiply -1 times 4. Multiply -4 times 2.
