    I posted this in the other thread but to no avail, can someone please help me factorise:

    2tanx + tanx(1-tan^2x)=0

    To show that tan^2x=3 and tanx=0

    I managed to prove tan^2x=3 but tanx=0, I cannot do at all.

    2tanx + tanx - tan^3x = 0
    3tanx - tan^3x = 0
    tanx(3-tan^2x) = 0

    So tanx = 0 and 3 - tan^2x=0

    So your answers are tan^2x=3 and tanx=0

    It's or! Jeez, if you're going to give full solutions you might as well do it properly.
