Question

What is the degree of the polynomial below?

x5 + 1 – 3x4 + 3x9 – 2x

A. 9
B. 5
C. 3
D. 4

Answer 1

A

Explanation:

A p e x

Answer 2

`x^(5) + 1 -3x^(4) + 3x^(9) - 2x`

=
`3x^(9) + x^(5) - 3x^(4) - 2x + 1`

The degree of a polynomial is the highest degree of its monomials with non-zero coefficients.

Hence, the degree of the above polynomial is 9.

Hence, the answer is A.
