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

Thank you

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

Yeah sorry my mistake, but calm down you don't have to be rude.

Sorry for that Dinasaurus!
