Solve for all the roots of x using Bairstow’s Method starting at r1 = 0.25 and s1 = 8.75 of the polynomial f(x) = x4+8x3-72x-81

The function, f(x) =x³ + x² – 13x + 3 has an x-intercept at x = 3. Use polynomial division to factor this polynomial and determine the other roots if they exist. Show your work! Leave answer(s) in exact form.
