# Factorization 2

### From Homeworkwiki

**1. Factor completely. If unfactorable, indicate that the polynomial is prime.**

**9x ^{5} – 9x^{3}**

**Solution:** 9x^{5} – 9x^{3}

= 9x^{3} ( x^{2} -1)

= 9x^{3} (x +1)(x-1)

**2. Factor completely. If unfactorable, indicate that the polynomial is prime.**

**x ^{2} + 32x + 33**

**Solution:** It cant be factored. So it is a prime.

**3. Factor completely. If unfactorable, indicate that the polynomial is prime.**

**s ^{14} – t^{6}**

**Solution:** It cant be factored. So it is a prime.
