Answer:

B. 8n²−16n=−68

Step-by-step explanation:

First - Distribute the n & 10

n * 8n & n * -6 = 8n² - 6n

10 * -n & 10 * 7  = -10n +70

Second -  Move the 2 by subtracting

8n² - 6n - 10n +70 = 2 -> 8n² - 6n - 10n +70 - 2 = 2 - 2

Third - Combine like terms

-6n - 10n = -16n

70 - 2 = 68

8n² - 16n + 68 = 0

Fourth - Move 68 by subtracting

8n² - 16n + 68 - 68 = 0 - 68

8n² - 16n = -68
