please help me solve this matlab problem. Thank you.

Problem 2: Application of the bisection bracketing method a) Apply your bisection code to find all the roots of the following polynomial and compare your results to those obtained using roots. f(x) = x3 6x2 + 12 b) Consider the natural frequency equation of the free vibration of an Euler-Bernoulli cantilever beam. The natural frequencies of the free vibration of a cantilever beam are determined from the roots of the following frequency equation: f(2)=1+cosh(2)cos(2)=0 Apply the bisection code to find the first three roots of the above frequency equation. Remember the important lesson learned in the pre-lab exercise
