## What is the term coefficient?

**are the number when you multiply a number and a variable**. For example 5a the coefficient in that term is 5 if you have 48e the coefficient is 48. So the coefficient is the number when you multiply a number times a variable.

## How do you write a coefficient?

For example 3 is the coefficient in 3x. Rather than using a multiplication sign between 3 and x the number is just written in front of a variable which means that the 3 and x are multiplied together. Instead of writing a + a + a + a you can express it as 4a with 4 being the coefficient.

## What is the coefficient of x² in √ 2x 1?

Dear student since there is no term of x² in the given expression. So coefficient of x² **is 0**.

## What is the coefficient of a polynomial?

Polynomial coefficients are **the numbers that come before a term**. Terms usually have a number and a variable (e.g. 2 x 2 2x^2 2×2 where 2 is the number and x is the variable). The number portion is the coefficient. … Simply stated it’s the coefficient of the leading term.

## How do you find the terms and coefficients of a polynomial?

We can find the **degree of a polynomial by identifying the highest power of the variable that occurs in the polynomial**. The term with the highest degree is called the leading term because it is usually written first. The coefficient of the leading term is called the leading coefficient.
