Question

What is true about the sum of the two polynomials?
6s2t – 2st2
4s2t – 3st2
a.) The sum is a binomial with a degree of 2.
b.) The sum is a binomial with a degree of 3.
c.) The sum is a trinomial with a degree of 2.
d.) The sum is a trinomial with a degree of 3.

Answer 1

combine like terms and simplify

6s^2 t + 4s^2t = ?
-2st^2 - 3st^2 = ?

then classify based on degree (highest sum of exponents in a single term) and type of polynomial (based on the # of terms)
