(20 points) Quadratic Equation Solver. Create a worksheet that uses the quadratic equation to find the real roots of a quadratic using the discriminant, if they exist. 3. The quadratic equation is given by: 2a and the discriminant is the part under the square root sign, the b -4ac. Recall that if the discriminant is positive, that there are 2 real roots, that if the discriminant is zero, there is one repeated real root, and if the discri negative, there are no real roots. For the following equations, you need to test the discriminant, print out if there are 2 real roots, 1 repeated real root, or o real roots. Then, if there are real roots, you need to calculate them. Verify that your solution is correct, if there are real roots. minant is Test for the following equations: x2 + 4x + 4 = 0 x2 + x + 2 = 0 4x2 + 15x =-9
