Re-arranging an inequality
I am trying to solve the inequality
[(4x - x^2 - 7) / (x^2 - 1)] >_ 3
I am still at the re-arranging stage and I get up to the point of
[(4x - x^2 - 7) / (x^2 - 1)] -3 >_ 0 which I understand how to get to.
But I do not understand how to get the below line of.
[(4x - 4x^2 - 4) / (x^2 - 1)] >_ 0

You have two expressions here: One with all the variables and the three. Put:
}{x^2 - 1 })

Thank you, that makes sense :)
