Question

What is the degree of the polynomial below?

Answer 1

$x^{5} + 1 -3x^{4} + 3x^{9} - 2x$

= $3x^{9} + x^{5} - 3x^{4} - 2x + 1$

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.
