Polynomials are of 3 different types and are classified based on the number of terms it has. The three types of polynomials are
Monomial :
A Monomial is an expression which contains only one term.
For examples,
5x, 3, 6a^{4}, -3xy
Binomial :
A binomial is a polynomial expression which contains exactly two terms. A binomial can be considered as a sum or difference between two or more monomials.
For examples,
– 5x+3, 6a^{4} + 17x, xy^{2 }+ xy
Trinomial :
A trinomial is an expression that is composed of exactly three terms.
For examples,
– 8a^{4}+2x+7 and 4x^{2} + 9x + 7
Note :
These polynomials can be combined using addition, subtraction, multiplication, and division but is never division by a variable.
Some examples of Non Polynomials are
1/x+2, x^{-3}, x^{1/3}
Determine if each expression is a monomial, binomial, trinomial, or not a polynomial.
