Question

sin^2 x + sin x - 2; where do I begin when factoring?

Answer 1

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

Answer 2

the factors are (a +2 ) ( a - 1) now replace a with sin x

factors will be ( Sin x + 2) ( Sin x - 1)

Answer 3

lol I just got that actually testing the other guys work (its deleted now)

Answer 4

=D thanks! I don't think we can factor any further, can we?

Answer 5

no

Answer 6
