$$\tan 3\mathrm{A}=\tan (2\mathrm{A}+\mathrm{A})=\frac{\tan 2\mathrm{A}+\mathrm{tanA}}{1-\tan 2\mathrm{AtanA}}$$$$\tan 3\mathrm{A}-\tan 3\mathrm{Atan}2\mathrm{AtanA}=\tan 2\mathrm{A}+\mathrm{tanA}$$$$\tan 3\mathrm{A}-\tan 2\mathrm{A}-\mathrm{tanA}=\tan 3\mathrm{Atan}2\mathrm{AtanA}\mathrm{proved}.$$
