Rewrite the expression 12(9 - 6n + 5) as a difference

Question

My math test is asking me this, but I forgot it in the time between the quiz that featured this skill and the unit test. It's the last one I have left to do but I have no clue how to do it.

Answer 1

12(9- 6n+5)

=12[(9+5) -6n]

=12(14-6n)

= 12(14) - 12(6n)

168 - 72n

that last expression above is the difference between 2 terms, which is probably what you want

in factored form it's 24(7-3n)

in prime factored form it's (2^3)(3)(7-n) or 2(2)(2)(3)(7-3n) but none of the factored forms are strictly a "difference"
