Answer:

B. (-2, -6)

Step-by-step explanation:

The constant term is the product of the values in the solution set. (Both A and B give 2·6 = 12.)

The coefficient of the x term (8) is the opposite of the sum of the values in the solution set. That is, the solutions add up to -8.

... A: 2+6 = 8 ≠ -8 . . . . not the solution set

... B: -2 +(-6) = -8 . . . . these values are the solution set.

The solution set is (-2, -6).

Answer:

n = 0, n =2

Step-by-step explanation:

Given

(n + 1) + 3(n - 1) = 2(n - 1)(n + 1) ← distribute parenthesis on both sides

n + 1 + 3n - 3 = 2(n² - 1), that is

4n - 2 = 2n² - 2 ( subtract 4n - 2 from both sides )

0 = 2n² - 4n ← factor out 2n from each term )

0 = 2n(n - 2)

Equate each factor to zero and solve for n

2n = 0 ⇒ n = 0

n - 2 = 0 ⇒ n = 2
