Factors and Greatest Common Factors
Today we will find the prime factorization and GCF of polynomials.
Students apply basic factoring techniques to second-and simple third-degree polynomials. These techniques include finding a common factor for all terms in a polynomial, recognizing the difference of two squares, and recognizing perfect squares of binomials.
