Learn how to solve discriminant of quadratic equation problems step by step online. Find the discriminant of the equation 6x^2+15x+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=6, b=15 and c=5. Replacing the values of a, b and c in the previous formula, we obtain. Multiply 4 times 6. Multiply 24 times -5.
