Is 1-(sin^6x+cos^6x)=(3sin^2x)(cos^2x) a Valid Trigonometric Identity?

In summary, verifying a trigonometric identity means proving its truth for all values of the variables involved. This is important for ensuring the accuracy of mathematical equations. The process involves using algebraic and trigonometric identities to manipulate the given equation until it is transformed into a known identity or is proven to be true. Some common identities that can be used include the Pythagorean, reciprocal, quotient, and double angle identities. If you are struggling, you can try different approaches or seek help from a teacher or tutor.

1-(sin^6x+cos^6x)=(3sin^2x)(cos^2x)

I got this far:

1-(sin^2x+cos^2x)(sin^4x-sin^2xcos^2x+cos^4x)=(3sin^2x)(cos^2x)
1-(sin^4x-sin^2xcos^2x+cos^4x)=(3sin^2x)(cos^2x)

I'd start by manipulating one of the sides.
