Create MATLAB code of Bracketing and Newton's Method that finds all roots of the following equation (Hint: There are three, real number roots for the equation.), and compare your result with the result from MATLAB provided function. x3-4x2-11x +30 -0 You may want to start with the range big enough to cover where roots would exist (-100 to 100 with increment of 4 would be a good start) Use Bracketing Technique to narrow the range down Then, apply the Newton's method to refine the
