Adding and Subtracting Polynomials Polynomials are expressions containing one or more than one term, with each term separated from  the preceding one by a plus or minus sign. The exponents on the variables in a polynomial are  always whole numbers. A polynomial has no maximum length. Some arithmetic operations with  polynomials need just common sense, but others require special techniques. In order to add and subtract polynomials successfully, you must understand what monomials,  binomials, and trinomials are; what constitutes “like terms”; and the difference between ascending  and descending order. Monomial, Binomial, and Trinomial monomial  is an expression that could be a numeral, a variable, or the product of numerals and

Unformatted text preview: variables. If the expression has variables, certain restrictions apply to make it a monomial. Variables must have whole number exponents. Variables do not appear under simplified radical expressions. Denominators do not contain variables. The following expressions are examples of monomials. 12, a , 3 t 2 , , y 3 , The following are expressions that are not monomials. A binomial is an expression that is the sum of two monomials. A trinomia l is an expression that is the sum of three monomials. A polynomial is an expression that is a monomial or the sum of two or more monomials....
