Question

what is ((n - 1)(6n - 6))?

a. (6n^2 - 12n + 5)
b. (6n^2 - 14n + 7)
c. (6n^2 - 10n + 6)
d. (6n^2 - 12n + 6)

Explanation:

Step1: Apply distributive property

$(n-1)(6n-6) = n(6n-6) -1(6n-6)$

Step2: Expand each term

$= 6n^2 -6n -6n +6$

Step3: Combine like terms

$= 6n^2 -12n +6$

Answer:

d. $6n^2 - 12n + 6$
