Question

Which is true about the degree of the sum and difference of the polynomials 3x5y – 2x3y4 – 7xy3 and –8x5y + 2x3y4 + xy3?

Answer 1

The sum has a degree of 6, but the difference has a degree of 7

Answer 2

For polynomials having to or more variables, degree can be of a term or of the polynomial. The degree of a term is the sum of the exponents in a specific term while the degree of a polynomial is the highest value of all the degree of a term in the given polynomial. For the polynomial given, the degree of the polynomial is 7.
