Answer:

Monomial

A monomial is an algebraic expression that has only one non zero term. Examples of a monomial expression:

a is a monomial in one variable a

10ab2 is a monomial in two variables a and b.

5m2n is a monomial in two variables m and n.

-7pq is a monomial in two variables p and q.

5b3c is a monomial in two variables b and c.

2b is a monomial in one variable b.

2ax/3y is a monomial in three variables a, x and y.

k2 is a monomial in one variable k.

Binomial

A binomial is an algebraic expression that has two non-zero terms. Examples of a binomial expression:

a2 + 2b is a binomial in two variables a and b.

5x3 – 9y2 is a binomial in two variables x and y.

-11p – q2 is a binomial in two variables p and q.

m + n is a binomial in two variables m and n.

b3/2 + c/3 is a binomial in two variables b and c.

5m2n2 + 1/7 is a binomial in two variables m and n.

Trinomial

A trinomial is an algebraic expression that has three non-zero terms. Examples of a trinomial expression:

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.

-7m5 + n3 – 3m2n2 is a trinomial in two variables m and n.

5abc – 7ab + 9ac is a trinomial in three variables a, b and c.

x2/3 + ay – 6bz is a trinomial in five variables a, b, x, y and z.

Polynomial

A polynomial is an algebraic expression that has one, two or more terms. Examples of polynomials:

2a + 5b is a polynomial of two terms in two variables a and b.

3xy + 5x + 1 is a polynomial of three terms in two variables x and y.

3y4 + 2y3 + 7y2 – 9y + 3/5 is a polynomial of five terms in two variables x and y.

m + 5mn – 7m2n + nm2 + 9 is a polynomial of four terms in two variables m and n.

3 + 7x5 + 4x2 is a polynomial of three terms in one variable x.

3 + 5x2 – 4x2y + 5xy2 is a polynomial of three terms in two variables x and y.

x + 5yz – 7z + 11 is a polynomial of four terms in three variables x, y and z.

1 + 2p + 3p2 + 4p3 + 5p4 + 6p5 + 7p6 is a polynomial of seven terms in one variable p.
