Write your MATLAB code of Bracketing and Fixed-Point Iteration 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 + 10x2 - x 10 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 Fixed-Point Iteration method to refine the answer. Verify your result using "roots" function in MATLAB
