This document provides examples of factorizing polynomials by:
1. Finding the roots of polynomials using the quadratic formula.
2. Factoring polynomials using the difference of squares and perfect square trinomial identities.
3. Factoring polynomials into irreducible factors.
The document contains several examples of factorizing polynomials of varying degrees up to degree 5. The examples illustrate the process of finding the roots and then factorizing the polynomials based on those roots.
