Study GuideAlgebra II–Polynomial ArithmeƟc1. Adding and SubtracƟng PolynomialsPolynomials are expressions made of one or moreterms.Each term is separated by aplus (+)orminus (−)sign.In a polynomial:•The exponents on variables must bewhole numbers(0, 1, 2, 3, …).•There isno limitto how long a polynomial can be.Some operations with polynomials are simple, but others require special methods.To add or subtract polynomials successfully, you need to understand:•Monomials, binomials, and trinomials•Like terms•Ascending and descending orderMonomials, Binomials, and TrinomialsMonomialAmonomialis a single term.•a number•a variable•or a number multiplied by variables.Rules for MonomialsFor an expression to be a monomial:1.Variables must havewhole number exponents.2.Variablescannot be inside square roots.3.Variablescannot appear in denominators.Preview Mode
