Factoring – We learned that the greatest common factor of the terms of a polynomial is the greatest common factor of the coefficients and the variable or variables, using the number of instances of the variable that are common to each term. We learned that when a trinomial is in the form x2 + bx + c, the factors are found by identifying a pair of integer factors of c that have a sum of b and then using the factors to write binomials that have a product equal to the trinomial.
