It is degree $3$ .

The degree of a polynomial is the degree of the highest degree term that has non-zero coefficient.

The degree of a term is the sum of the powers on the variables in that term. A non-zero constant term has degree $0$ .

This polynomial can be written as

$3x^2y^1-5x^2$

And the degree of each term is

$3x^2y^1rarr3$
$5x^2rarr2$

Since $3>2$ , the degree of the entire polynomial is $3$ .

What is the degree of the polynomial 3x^2y-5x^23x^2y-5x^2?
