# Example of trinomial algebraic expressions

Dear Student,

Expression with three terms, where the terms are unlike, is called a

**trinomial**.Example: 2

*x*^{2}–3*x*+ 1, – 2*xy*+ 5*y*+ 6*x*, etc.Expression with four terms, where the terms are unlike, is called a

**quadrinomial.**Example: 2

*x*^{2}–3*x*+ 15*y*+ 1, – 2*xy*+ 5*y*+ 6*x*+ 13 etc.In general, the expression with one or more terms is called a

**polynomial**.Example: 15

*x*^{4}+ 2*x*^{2}–3*x*+ 15*y*+ 1, 19*xy*^{5}+ 17*x*^{3}*y*^{9 }– 2*xy*+ 5*y*+ 6*x*+ 13 etc.In fact binomials, trinomials and quadrinomials are also polynomials.

Regards!
