Oh right!! Cancelling the x's How silly of me. Thanks.
You see, I understood your 'divide by x^4' to result in changing the denominator to x^8. I didn't mean to sound rude either , just matter-of-fact like since you told me that it's 'easy' yet I could already solve the problem... Peace.
What should I do?
