ONLY NUMBER 4 PLEASE!

Use MATLAB to carry out the following multiplication of polynomials: (x + 1.4)(x - 0.4) x(x + 0.6)(x - 1.4) Plot the polynomial for-1.5 lessthanorequalto x lessthanorequalto 1.5. Divide the polynomial -0.6x^5 + 7.7x^3 - 8x^2 - 24.6x + 48 by the polynomial -0.6x^3 + 4.1x - 8. Divide the polynomial x^4 - 6x^3 + 13x^2 - 12x + 4 by the polynomial x^3 - 3x^2 + 2. The product of three consecutive integers is 1, 716. Using MATLAB's built-in function for operations with polynomials, determine the three integers. The product of four consecutive even integers is 13, 440. Using MATLAB's built-in function for operations with polynomials, determine the four integers
