The term polynomial is a mixture of poly or many, and nomial which means terms. It is ideally an expression that is composed of exponents, variables, and constants. It is proved through equations like addition, multiplication, and subtraction. The monomial, polynomial, trinomial, and binomial is classified by determining the number of terms present in an equation.
A monomial is an expression that includes one term which is non zero. Whereas a binomial is a polynomial variant containing two terms. It is seen that a binomial can be a product or sum of two or more monomials. A trinomial exactly includes three terms.
