Answer 2

Answer:

An example of a trinomial with degree 21 is $3x^{21} - 4x +2$

Step-by-step explanation:

To find,

A trinomial with degree 21

Recall the concepts

An algebraic expression is said to be a polynomial if the exponents of the variables are whole numbers and numerical coefficients are real numbers

A trinomial is a polynomial with three terms

The degree of the polynomial is the highest power of the variable in the polynomial

Solution

Consider the algebraic expression

$3x^{21} - 4x +2$

In this algebraic expression, all the numerical coefficients (3,-4,2) are real numbers and all exponents of the variable are (21,1, 0) are whole numbers

Hence this expression is a polynomial

Since there are three terms in this polynomial, it is a trinomial

The exponents of the variable are 21,1,0

The highest exponent of the variable = 21

Hence, the degree of this polynomial = 21

This is an example of a trinomial with degree 21.

∴An example of a trinomial with degree 21 is $3x^{21} - 4x +2$.
