Learn how to solve discriminant of quadratic equation problems step by step online. Find the discriminant of the equation z^4-2z^32z^2-2z+1. 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=-2 and c=1. Replacing the values of a, b and c in the previous formula, we obtain. Multiply 4 times 2. Multiply 8 times -1.
