Answer:
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.
