Which expression correctly shows x^6+2x^3+1 factored completely over the integers?

a. (x^2+1)(x4−x^2+1)

b. (x^3+1)2

c. (x+1)(x^2−x+1)

d. (x+1)2(x^2−x+1)2

Option D, (x + 1)^2(x^2 - x + 1)^2

Step-by-step explanation:

Step 1:  Factor

x^6 + 2x^3 + 1

(x + 1)^2(x^2 - x + 1)^2

 Option D, (x + 1)^2(x^2 - x + 1)^2

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
