3a^2/a^2+a+1 2a/a-1 a^3/a^3-1
I know that in order to find the LCD you would have to multiply the top and bottom of the fraction but on this one I just keep getting stuck :( Help! Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! 3a^2/a^2+a+1 2a/a-1 a^3/a^3-1

Factor each denominator:
a^2+a+1 is not further factorable.
a-1 is not further factorable.
a^3-1 = (a-1)(a^2+a+1)
-------------------------
LCD = (a-1)(a^2+a+1)
