Question

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

a. $6n^{2}-12n + 5$
b. $6n^{2}-10n + 6$
c. $6n^{2}-12n + 6$
d. $6n^{2}-14n + 7$

Explanation:

Step1: Expand using distributive property

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

Step2: Distribute terms

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

Step3: Combine like terms

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

Answer:

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