Question

an
gire example of a binomial of degree in
and of trinomial of degree ss.​

Answer 1

(i) x

(ii) 3x^{20}+4

(iii) x^{2}+2x+5

Solution

Monomial: It is an algebraic expression consisting of only one term.

Example: 2x

Binomial means consisting of exactly two terms. These terms should not be like terms.

For example: x^{2}+1 is a binomial

x + 2x is not a binomial as these are like terms.

Trinomial means consisting of exactly three terms. These terms should not be like terms.

For example: x^{2}+2x+1 is a trinomial

x + 2x is not a binomial as these are like terms.

Degree: Degree of an expression is the highest power of the monomial present in the expression with non-zero coefficient

(i) monomial of degree 1:

2x, x, y, 7y etc.

(ii) binomial of degree 20:

3x^{20}+4

(iii) Trinomial of degree 2:

x^{2}+2x+5
