Learn how to solve discriminant of quadratic equation problems step by step online. Find the discriminant of the equation 121x^2-176x+64=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=121, b=-176 and c=64. Replacing the values of a, b and c in the previous formula, we obtain. Multiply 4 times 121. Multiply 484 times -64.
