Question 709590: I need (x+3)^3 simplified please and thank you.
Answer by josh_jordan(263)   (Show Source):
You can put this solution on YOUR website! 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
