You can get this answer by multiplying the two polynomials and then simplifying. See the steps below: (4x^2 - 5)(x + 3) ---> Now multiply the two parenthesis. 4x^3 - 5x + 12x^2 - 15 ---> Arrange the numbers by decreasing exponents. 4x^3 + 12x^2 - 5x - 15
No simplifying can be done since there are no like terms. </span>
