Question

Verify the trig problem (equation in the comments)

Answer 1

\[\frac{ \tan ^{2} x-1 }{ \sec ^{2} x+3tanx+1 } = \frac{ tanx-1 }{ tanx+2 }\]

Answer 2

u have to convert sec^2 x to tan^2 x + 1, first

Answer 3

we try to proving LHS be equal to RHS

Answer 4

Alright. Now what? Should I write the numerator of the LHS as a difference of squares?

Answer 5

so, the LHS can be
