I am supposed to factor a trig expression.

the expression is:

1-2 sin^2x+sin^4x

Any help is appreciated!

Jhevon,

When I factored, I came up with (1-sin^2x)^2=cos^4x. Is this correct? Vrod guy, I hope I was able to come up with the correct answer for you. - Apr 20th 2009, 06:09 PMvrod guy
Scott, Are you sure this is correct? Does anyone else agree with Scott?

Not if you were asked to factorise.
