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.

Option b). The sum is a binomial with a degree of 3.

Step-by-step explanation:

The given polynomials are,

1). 6s²t – 2st²

2). 4s²t – 3st²

Sum of polynomials

Sum = (6s²t – 2st²

) + (4s²t – 3st²)

Sum = 6s²t + 4s²t  -  2st² - 3st²

Sum = 10s²t - 5st²

degree = 2 + 1 = 3

It is a binomial with degree of 3.

Therefore the correct answer is option b).The sum is a binomial with a degree of 3.
