Question

Which expression has a coefficient of positive 1 for the the term n?

5n² + 6n-1
2n2 - 5n + 1
3n²+ n-2
40² - n +9
Someone pls help quick

Answer 1

3n^2+n-2

Explanation:

Coefficient is the number that we multiply an expression that contains a variable. In all the expressions above the variable is n.

Some examples:

Coefficient of n^2 is 1.

Coefficient of n in n^2+2n+1 is 2.

Solution:

In 5n^2+6n-1 the Coefficient of n is 6.

In 2n^2+5n+1 the Coefficient of n is 5.

In 40^2 - n +9 the Coefficient of n is - 1.

In 3n^2 +n - 2 the Coefficient of n is POSITIVE 1.

We tend to not write 1*n because 1*n=n.
