Question

PLEASE HELP!

What is the coefficient of the term of degree 4 in this polynomial below?

Answer 1

Given:

`x^(8)+2 x^(4)-4 x^(3)+x^(2)-1`

To find:

The coefficient of the term of degree 4.

Solution:

Given polynomial is
`x^(8)+2 x^(4)-4 x^(3)+x^(2)-1`.

Degree means power of the variable x.

The term which contains degree 4 is
`2x^4`.

Coefficient of
`2x^4` is 2.

Therefore the coefficient of the term of degree 4 in the polynomial is 2.
