=[4 - (3c - 1)][6 - ( 3c - 1)]
=[4-3c+1][6-3c+1]
=[5-3c][7-3c]

then distribute in with FOIL method... hold on a sec i'll give it a try and see if it matches your answer

Answer 3

=[5-3c][7-3c]
=35-15c-35c+9c^2
=35-50c+9c^2

i've gotten a -50c term instead of your -36c team... but i might have messed up... let me check again.

Answer 4

Whoops... i made a mistake
=[5-3c][7-3c]
=35-15c-21c+9c^2
=35-36c+9c^2

Sorry about that. So yes, your initial answer is correct.
