Let us recall that algebra is the branch of mathematics which deals we come across two quantities, viz. , constants & variables . Whereas a constant is a fixed value; a variable take different numerical values. These constants & variables are related to each other with the help of different mathematical operations of add, subtract, multiply & divide. Such a relation of constants & variables is called an algebraic expression. The constants & variables , when combined with the operation of multiplication or division form the terms of the algebraic expression & such terms are , in turn , separated from each other by addition (+) or subtraction (-) . Example : 2x-3y+xy -8 is an algebraic expression whose terms are 2x , -3y , xy and -8 .
Depending on the number of such terms in an expression, the algebraic expression may be categorized into the following groups:
Monomials: “Mono” means one. So an expression with just one term is called a monomial . e.g. , 3y , 2xy , 7 , 5z are monomials .
Binomials: “Bi” means two. So an expression with two terms is called a binomial . e.g. , 3y - 2xy , 7 + 5xz are binomials .
Trinomials: “Tri” means three. So an expression with three terms is called a trinomial . e.g. ,12x+ 3y -6 , 2xy + 7 - 25z are trinomials .
Polynomials: “Poly” means more than one . So an expression with more than one term or in other words, with two or more terms is called a polynomial . Binomials & trinomials are a part of polynomials.
