Please complete the maths ASAP! I will upvote if it's done appropriately.

Determine the real root of f(x)=26+85x91x2+44x38x4+x5 using the bisection method. Employ initial guesses of xl=0.5 and xu=1.0. Iterate the process until the approximate error falls below a stopping criterion of s=10%. Note that you must show the detail calculation of the first iteration
