Answer 1

To factor the polynomial \(13x^{11} - 117x^3\) completely, we can start by factoring out the greatest common factor (GCF).

1. First, we can factor out \(13x^3\):
\[
13x^{11} - 117x^3 = 13x^3(x^{8} - 9)
\]

2. Now, we will focus on factoring \(x^{8} - 9\). This expression is a difference of squares:
\[
x^{8} - 9 = (x^{4})^2 - 3^2 = (x^{4} - 3)(x^{4} + 3)
\]

3. Putting it all together, we have:
\[
13x^{11} - 117x^3 = 13x^3(x^{4} - 3)(x^{4} + 3)
\]

Thus, the complete factorization of the polynomial is:
\[
\boxed{13x^3(x^{4} - 3)(x^{4} + 3)}
\]
