1. Terms Monomials separated by addition or subtraction signs Polynomials A monomial or the sum of monomials Binomial---2 terms Trinomial---3 terms Monomial---1 term---a number, variable or product of a number and variable

2. Degree of a term the sum of the exponents of the variables of a term Standard Form (descending order) Polynomials written greatest to least by degree 6x 3 - 4x 2 + 6x - 7

3. (4x 2 + 6x + 7) + (2x 2 – 9x +1) Adding Polynomials Rewrite vertically, then combine like terms (4x 2 + 6x + 7) + (2x 2 – 9x + 1) 6x 2 - 3x + 8

4. (2x 3 + 5x 2 – 3x) - (x 3 – 8x 2 + 11x) Subtracting Polynomials Distribute (-1) Rewrite vertically Combine like terms (2x 3 + 5x 2 – 3x) (-x 3 + 8x 2 – 11x) x3x3 + 13x 2 – 14x
