\alpha ,\,\,\beta

are the solutions of

a\,\,\tan \,\,\theta + b\,\,\sec \,\,\theta = c

, then

\tan \,\,\left( {\alpha + \beta } \right) =

View answer and explanation

Correct option: A

\frac{{2\;\,ac}}{{{a^2} - {c^2}}}

Option B (

\frac{{2\;\,ac}}{{{{a^2} - {c^2}}}}

) is the correct answer because it is derived from the trigonometric equation and the properties of roots of a quadratic equation.
