Polynomial – a monomial or the sum of monomials

Types of Polynomials

• Binomial- the sum of two monomials

• Trinomial – the sum of three monomials

Examples

State whether the following is a polynomial and if it is identify the type.

Expression Polynomial? Monomial, Binomial, or Trinomial?

2x-3yz Yes Binomial

8n3+5n-2 No None of these

-8 Yes Monomial

4a2+5a+a+9 Yes Trinomial

Application!

Write a polynomial to represent the area of the red region.
