3. Extra credit: Write a Python program that solves any quadratic equation that has two roots. For this one, since we need to bracket the root to start the search, we ask the user to type in a, b, and c and an initial value for x where y is positive and an another where y is negative (if they aren't, complain to the user and stop). Then we search for the root using bisection search between those two user-input guesses for x. Print out the number of iterations needed. (30 points of extra credit. Any attempt will be worth some points.) Turn this in as p3_bisection.py. solving ax^2 + bx + c = 0: a = 1 b = -1.5 C = -1 low bracket = -100 high bracket = 0 one root is: -0.50000 took 41 iterations
