Re: Simplify the following:Hi EbenezerSon The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #3 20130710 04:33:00

Re: Simplify the following:Hi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #5 20130711 04:54:40

Re: Simplify the following:hi EbenezerSon Code:[math]\frac{x^2 + 1}{x  1}[/math] gives this: and if you click on someone else's Latex you can see how they constructed it. Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #7 20130711 05:09:21

Re: Simplify the following:hi Ebenezerson I think you'll need to multiply these brackets out like this Then you can start to simplify. Can you fill in the dots ? Alternative way to do this: difference of two squares: Have you met this before ? If so, you could put p = 2m + 2k and q = m  2k Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #9 20130711 05:23:23
Re: Simplify the following:Yes, with the difference of two square I have met that before. #10 20130711 05:36:43
Re: Simplify the following:Shall I show you how I would do it? It looks to me like you should do all the others using the difference of two squares. But for (3) and (4), you'll have to work out what the two squares are. Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #11 20130711 05:39:31

Re: Simplify the following:I see it the following: #15 20130711 06:01:48
Re: Simplify the following:
Please I am not grasping what you mean could you demonstrate? Or you mean: #17 20130711 06:07:36
Re: Simplify the following:Err sir I have understood you well! with (1) and (2). :) #18 20130711 06:10:53
Re: Simplify the following:But please help me solve the third and the fourth ones. #19 20130711 06:18:58
Re: Simplify the following:At first, I did not spot that this is the difference of two squares. But then I noticed that (q^2  6qr + 9r^2) is a perfect square: So try this: put P = 3p and Q = (q  3r) and use Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #20 20130711 06:27:21
Re: Simplify the following:= (3p)^2  (q 3r)^2 #22 20130711 06:38:46
Re: Simplify the following:Candidly speaking sir, I cant tell or explain why that negative sign should appear there, to be frank! Last edited by EbenezerSon (20130711 06:40:55) #23 20130711 06:42:52
Re: Simplify the following:Please an assistance, please and why it should appear. #24 20130711 06:43:06
Re: Simplify the following:put P = 3p and Q = (q  3r) and use so P+Q = 3p +(q3r) and P  Q = 3p  (q3r) When you remove the brackets the q becomes minus and the 3r becomes + So can you see what the answer should be ?

Re: Simplify the following:Okay sir! but could you explain with an illustration, how you got the (q  3r)^2 ? Last edited by EbenezerSon (20130711 07:28:22)
