Question

What is true about the sum of two polynomials?

Answer 1

Answer:

The sum is a binomial of degree 3.

Step-by-step explanation:

You are adding two binomials. Each binomial has two terms.

The terms 6s^2t and 4s^2t are like terms and combine to give the sum 10s^2t.

The terms -2st^2 and -3st^2 are like terms and combine to give the sum -5st^2.

The sum of the binomials is the binomial 10s^2t - 5st^2.

Since each original binomial is of degree 3, the sum is also of degree 3.

Answer: The sum is a binomial of degree 3.
