Question

Plzzzzz answer it as soon as possible

Answer 1

sin^2 6x - sin^2 4x = (sin6x-sin4x)(sin6x+sin4x)

                              = (2cosxsin5x)(2sinxcos5x)

                              = (2sinxcosx)(2sin5xcos5x)

                              = sin2x.sin10x Ans.

That's what i got. I Hope that this incorrect answer will become the foundation of tomorrow's correct answers.

With deep irony.
