amistre64 · Answer

3^3 = 27; and --+ = +

anonymous · Answer

wait so what would the answer be ?

amistre64 · Answer

i would assume that it would be the one that has a + and a 27 in close proximity ...

amistre64 · Answer

my other assumption being that I thought you needed help in determining the solution; not in being tutored on the subject.

anonymous · Answer

$$ (x-3)^2(x+3) = 27-9 x-3 x^2+x^3 $$

anonymous · Answer

its a +9x

sasogeek · Answer

you mis-typed one of your answers... the answer is the second one with +9x actually being -9x :) so you'd have what ffm typed. x^3-3x^2-9x+27
