Question 709590
To simplify, first expand the factor:  (x + 3)^3 = (x + 3)(x + 3)(x + 3)


Next, multiply (x + 3)(x + 3) using the FOIL method.  This results in


x^2 + 6x + 9


Then, multiply this result by (x + 3):


(x^2 + 6x + 9)(x + 3) -----> x^3 + 3x^2 + 6x^2 + 18x + 9x + 27


Finally, combine all like terms to determine our final answer:


x^3 + 9x^2 + 27x + 27
