A trigonometric expression is given to us and we need to simplify it and find out the value.

Given Expression :-

$\sf\implies 3(tan^2\theta - sec^2\theta )$

Using Identity :-

$\sf\implies sec^2\theta - tan^2\theta =1$

So that ,

$\sf\implies tan^2\theta -sec^2\theta = -1$

Substitute the value :-

$\sf\implies 3(tan^2\theta - sec^2\theta ) \\\\\sf\implies 3 *(-1) =\boxed{\red{\sf -3}}$

Hence the required answer is -3 .
