+%28x%2B3%29%5E3+
is the same as ...
+%28x%2B3%29%28x%2B3%29%28x%2B3%29+
Concentrating on just the first two quantities ...
+%28x%5E2+%2B6x+%2B9%29%28x%2B3%29+
The distribute through the third
+x%5E3+%2B6x%5E2+%2B+9x+%2B+3x%5E2+%2B+18x+%2B+27+
combine like terms
+x%5E3+%2B9x%5E2+%2B+27x+%2B+27+
You got it!!
