Pregunta: Solve tanxsecx-2tanx=0 for all real values of x.

Factor $\tan \left(\mathrm{x}\right)$ out of $\tan \left(\mathrm{x}\right)\sec \left(\mathrm{x}\right)-2\tan \left(\mathrm{x}\right)$ .

$\tan \left(\mathrm{x}\right)(\sec \left(\mathrm{x}\right)-2)=0$

If any individual factor on the left side of the equation is equal to $0$ , the entire...
