Expert Solution
Step 1

It is given that the function is fx=0.7x5-8x4+44x3-90x2+82x-25. We have to find the real

root of the function between the points a=0.5 and b=1.

We have to use the bisection method. This method is an iterative technique which finds the root

by repeatedly dividing the interval.
