![]() Notice that in the final answer each term of one parentheses is multiplied by every term of the other parentheses. If we now expand each of these terms, we have Since (3x + z) is in parentheses, we can treat it as a single factor and expand (3x + z)(2x + y) in the same manner as A(2x + y). Now consider the product (3x + z)(2x + y). In the previous section you learned that the product A(2x + y) expands to A(2x) + A(y). Use the distributive property to multiply any two polynomials.In each of these examples we are using the distributive property. ![]() Notice each term is multiplied by 2x.Īgain, each term in the parentheses is multiplied by 3y 2Īgain, each term in the parentheses is multiplied by 3y 2. Placing 2x directly in front of the parentheses means to multiply the expression in the parentheses by 2x. We now extend this idea to multiply a monomial by a polynomial. In the process of removing parentheses we have already noted that all terms in the parentheses are affected by the sign or number preceding the parentheses. If a polynomial has three terms it is called a trinomial. If a polynomial has two terms it is called a binomial. Special names are used for some polynomials. Generally, if there is more than one variable, a polynomial is written in alphabetical order.
