A polynomial consists of constants, variables and exponents. Polynomials are named based on the number of terms they have. Polynomials with 1 term are called monomials. Those with 2 terms are called binomials, and the ones with 3 terms are called trinomials.

- Introductiona)What is a polynomial?
- Review on Variables, Coefficients, and Expressions
- What are Monomials, Binomials, and Trinomials?
- What are the Degree, Leading Term, and Constant term of a polynomial?
- Name polynomials based on degree: Quadratic, Cubic, Quartic, Quintic, etc.

b)How to find the degree of a polynomial? - 1.Determine the number of terms and the name for each of the expression.a)$- 5{y^2}$b)$2{x^2} + 4x + 6$c)$- 7.3$d)$y^3 + ay + nx - x^2$
- 2.Find the degree and number of terms for each of the following expression.a)$2xy - 3{y^2} + 6$b)$4{a^3} + a$c)$- 4$
- 3.Write the expression for each set of the algebra tiles.a)
