Answer 1

Bribery, eh?

Answer 2

not bribery just incentive. :) I am like the worst at this stuff!

Answer 3

First, pull out a 3
\[3(s^2-18s-81)\]
That's as far as that goes. If the -243 was a typo and it was supposed to be +243, factor s^2-18s+81. Notice that it is the square of a binomial.
\[3(s-9)^2\]

Answer 4

it is +243 i'm sorry

Answer 5

Yeap should have been 3s^2-54s+243
