(Algebra: solve quadratic equations) Write a function for solving a quadratic equation using the following header:

def solveQuadratic(eqn, roots):

The coefficients of a quadratic equation are passed to the list eqn and the noncomplex roots are stored in roots. The function returns the number of roots. Write a program that prompts the user to enter values for a, b, and c and displays the number of roots and all noncomplex roots.

Sample Runs:

Enter a, b, c: 1.0, 3, 1

The roots are -0.381966 and -2.61803

Enter a, b, c: 1, 2.0, 1

The root is -1

Enter a, b, c: 1, 2, 3

The equation has no real roots
