3. [10 marks] Write down the roots of the polynomial: W(x) = (x-1)(x-2)... (x 20). Now perturb one of the coefficients by a very small amount to create a new polynomial p(x) = W(x) 2-23,19. (1) Find the all the roots of this new polynomial using MATLAB. Is the problem of finding the roots of W (x) sensitive? Explain
