when you add up the exponents in each term, you get 3, 2 ,3, 1 respectively 
the highest number is 3, pick that one

how does that help her?

anonymous · Answer

The degree of the polynomial is equal to the highest exponent, but in this case you have
x^2y^1
adding those exponents, you have a third degree polynomial.
