In this problem, you will use Bisection method to find a root of a polynomial. Write a C program to find a root of a cubic polynomial p(x)=a x^3 + b x^2 +c x +d=0 in the interval [-50,50] if it exists. You program will first prompt for and read the coefficients a, b, c, and d of the polynomial. Step#1: Locate the interval [x0,x1] containing the root as follows: - fix x0 to -50 . Also initialize x1 to -50 - for each value of x starting from -50 to 50 with increment of 1 If |p(x)| display the value of x as the root and stop. If p(x)*p(x0) assign x to x1 and get outside the loop (using break statement) Step#2: Finding the root: - After the loop, if x1 is still -50 -> display No root found inside [-50,50] and terminate - If not -> The root is in the latest interval [x0,x1]. Then apply the following bisection procedure method: o Compute xm=(x1+x0)/2 which represents the middle of the interval [x0,x1] o While |p(xm)| >= epsilon If p(x0)*p(xm) root between x0 and x1, so x1 = xm if p(xm)*p(x1) >0 -> root between xm and x1, so x0 = xm update xm=(x0+x1)/2 - Display the value of the root found and the number of iterations (repetitions) to obtain the root. Note: Define epsilon as a constant with a value = 1E-6
also, write the programme in two different ways.
