Question

what is true about the completely simplified sum of the polynomials 3x2y2 - 2xy5 and -3x2y2 + 3x4y

Answer 1

answer choices (please post these next time)
The sum is a trinomial with a degree of 5.
The sum is a trinomial with a degree of 6.
The sum is a binomial with a degree of 5.
The sum is a binomial with a degree of 6.

Answer 2

take the sum

(3x2y2 - 2xy5) + (-3x2y2 + 3x4y)

by combining like terms. for example, 3x2y2 and -3x2y2 are like terms. once your like terms are combined, see how many terms you have left (3 if it's a trinomial, 2 for binomial) and what the highest sum of exponents for a single term is (that'll be your degree)
