Problem:
Demonstrate the use of the bisection method to find roots of third degree polynomials:

f(x) = x3 + a x2 + b x1 + c

Visualization:
Enter the coefficients of f:

f(x) = x3 + x2 + x1 +

Enter the endpoints of an interval, r and s such that f(r) f(s) < 0:

r =
s =

Enter the number of steps: (Maximum = 50)

n =
