Factor out a 4 and use the difference of squares.
Give it a try. It is similar to the earlier ones we did.
hmm so whats the correct factoring? becuase heres his reasoning...
27t^2+18t+9
so
3t^2-2t+1
and then you do
(1x-1) (3x+1)
and thats because FOIL
so -1x(3x)=-3x
and -1(1)=2x
so the answer when you put them together is -2 which is in the 3t^2+18t+9...
i dont get that...does it make sense?
and no i DID copy it right thats why im so confused too..
