Question

Which of the following polynomials corresponds to the subtraction of the multivariate polynomials 19x 3 + 44x 2 y + 17 and y 3 - 11xy 2 + 2x 2 y - 13x 3?

Answer 1

the formatting is a bit difficult to understand but you should look for
1. the choice where two terms are being subtracted
2. the choice where one or more of the terms are multivariate (that have more than one variable, so for example, xy)
