What is true about the sum of the two polynomials? 6s2t - 2st 4s? t-3st? the sum is a binomial with a degree of 2. the sum is a binomial with a degree of 3. the sum is a trinomial with a degree of 2. the sum is a trinomial with a degree of 3.

B is the correct answer.

Explanation :

The sum is 10s^2t-5st^2.  With two separate sections, it is a binomial, and since the sum of the powers of the variables is 2+1=3, it has a degree of 3.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
