Yet another one (xD). Let f(x) = x^2 + 3x - 4 and g(x) = x + 5. Find f(x) · g(x)?

Question

-Options-
$$x^3 + 3x^2 + 16x - 20$$
$$x^3 + 5x^2 + 14x - 20$$
$$x^3 + 8x^2 + 11x - 20$$
$$x^3 + 9x^2 + 19x - 20$$

My only problem with this equation is that I don't know how to solve f(x) and g(x) equations
