Answer 1

Answer:

Let a+ b = x and a - b = y

$\tan( \alpha ) + \tan( \beta ) =x ( 1 - \tan( \alpha ) \tan( \beta ) ) \\ \tan( \alpha ) - \tan( \beta ) =y( 1 + \tan( \alpha ) \tan( \beta ) )$

Now it am giving you hint try to solve

Add both equation and then subtract

there will be terms (x-y) and (x+y) Solve from them .

If you got problem let me know
