polynomial-a polynomial is an expression consisting of indeterminates (also called variables) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.
example:a single indeterminate x is x2 − 4x + 7.
binomial-Binomial is a polynomial with only terms
example:x + 2 is a binomial, where x and 2 are two separate terms
trinomial-A trinomial is an algebraic expression that has three non-zero terms
example: x + y + z is a trinomial in three variables x, y and z. 2a2 + 5a + 7 is a trinomial in one variables a. xy + x + 2y2 is a trinomial in two variables x and y.
monomial-A monomial is a polynomial, which has only one term. A monomial is an algebraic expression with a single term but can have multiple variables and a higher degree too.
example:9x3yz is a single term, where 9 is the coefficient, x, y, z are the variables and 3 is the degree of monomial.
