[(5)/(2x-8)]+[(3x^2+15)/(x^3-4x^2+5x-20)]Stephen La Rocque lui répond. Rational expressions 2005-11-15 Zach pose la question :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.Penny Nom lui répond. A rational arithmetic expression 2005-09-14 Vijay pose la question :How to simplify following Grade 9 math problem: (4/-9) X (-21/-32) X (-3/14)Penny Nom lui répond. Rational expressions 2004-09-24 A student pose la question :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.Claude Tardif lui répond. Subtracting rational expressions 2003-05-10 Simone pose la question :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!Penny Nom lui répond.
