OpenStudy (rajee_sam):
Put a = sin x and rewrite the equation as a^2 + a -2. after you factor it like regular quadratic replace a with sin x
OpenStudy (rajee_sam):
the factors are (a +2 ) ( a - 1) now replace a with sin x factors will be ( Sin x + 2) ( Sin x - 1)

OpenStudy (anonymous):
=D thanks! I don't think we can factor any further, can we?
OpenStudy (rajee_sam):
no
