	Rational polynomial expressions		2007-06-09
		From a student: I have a question that continues to lead me to the answer x/(x - 1) but according to my math book, the answer should be 1/(x - 1). Who is right? Who is wrong? Here is the question: (x^2 - 6x - 27)/(x^2 - 11x + 18) DIVIDED by (x^3 + 2x^2 - 3x)/(x^2 - 2x) Answered by Stephen La Rocque.

	Rational expressions		2005-11-15
		From Zach: I can solve easy problems such as (x/2)+3=2+(3x/4). That is easy because the Lowest Common Denominator is 4. But what really gets me stuck is a problem like this one. (6/x-2) = ( 21/(x-2)(x+2) )+ 1. Answered by Penny Nom.
	2x/x^2-9 - 6/x^2+x-12		2005-09-27

		From Vijay: How to simplify following Grade 9 math problem: (4/-9) X (-21/-32) X (-3/14) Answered by Penny Nom.
	Rational expressions		2004-09-24
		From A student: In general, I understand rational expressions except when it comes to solving problems such as: x+y/2x-y - 2x/y-2x or m-4/3m-4 + 3m+2/4-3m I am confounded by the issue of having to find a common denominator. For example, if I tried to solve these problems by multiplying both denominators they would still be uncommon. Answered by Claude Tardif.
	An equation with rational terms		2004-06-17
		From Louise: simplify the expression (a2+n2)/2n = a2 + (a2-n2)/2n Answered by Penny Nom.
	Subtracting rational expressions		2003-05-10
		From Simone: hi, i'm totally lost. i understand that you need to find a lowest common denominator to subtract two fractions (rational expressions) with different denominators. but what if the denominators are "x-1" and "x". is x the common denominator? if so what happens to the "-1"? do you know of any live online help i can get with the following: 3/(x-1) - (1-2x)/x i've looked through my notes and have no examples that quite match that i can follow to get through it. please help! Answered by Penny Nom.
	Excluded values		2003-02-22
		From Josh: Why do you think it is necessary to include the "excluded values" when you write your answers to rational expressions? Answered by Penny Nom.
