Expand a Binomial Raised to a Power
-$$( x + 3 ) ^ { 3 }$$
A) $x ^ { 3 } + 9 x ^ { 2 } + 27 x + 27$
B) $x ^ { 3 } + 3 x ^ { 2 } + 9 x + 27$
C) $3 x + 9$
D) $x ^ { 3 } + 27$

Question

Quizplus · Accepted Answer

To expand $(x + 3)^3$, use the binomial theorem or distribute the terms manually. The correct expansion is $x^3 + 3(x^2)(3) + 3(x)(3^2) + 3^3$, which simplifies to $x^3 + 9x^2 + 27x + 27$.
