Simpler: -(x - 2) = 2 - x, and x - 2 = -(2 - x), so convert the original equation to:Ok these were my steps... (im going to explain in words instead of pictures because it took me forever to post that last message)
1. factored the 4-x^2 into -(x+2)(x-2).
You might want to check the cancellation on the right-hand side. One of the factors of x2 - 4 should have cancelled off!4. i simplified to get -x^2/-(x^2-4) = 5/(x+2)
5. cross multiply... -x^2(x+2) = -5(x^2-4)
