Algebraic fractions 2008-10-06 From Kayla:(x^2-9)/x times (x^3-4x)/(x^2+5x+6)Answered by Harley Weston. 1/3-5/6=1/x, solve for x 2008-05-01 From Lavada:1/3-5/6=1/x How do I solve this problem.Answered by Penny Nom. Simplify 5x^5/8 / 15x^2/12 2008-04-18 From Kyler:5x^5/8 / 15x^2/12 Divide the rational expressions. Simplify the results.Answered by Penny Nom. How would I graph: x - 2 divided by x^2 - 4? 2008-03-19 From Sean:How would I graph: x - 2 divided by x^2 - 4 using a method in extreme values of functions or completing the square x - 2/ x^2-4Answered by Stephen La Rocque. Subtracting rational expressions 2007-10-09 From Pamela:Subtract: ```6p – w __ 4c + p w – 4 w – 4 ```Answered by Stephen La Rocque. Simplifying a quartic rational expression using long division 2007-06-14 From Megan:x+2/12x^4+17x^3+0x^2+8x-40=Answered by Stephen La Rocque and Penny Nom. 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. Simplifying a rational expression 2007-04-29 From Tamika:X^2 + 10X + 24 ______________ X + 6 SIMPLIFY EACH RATIONAL EXPRESSION (IF YOU CAN'T SIMPLIFY IT, WRITE ALREADY SIMPLIFIED)Answered by Stephen La Rocque. Adding and Subtracting Rational Expressions 2007-03-21 From Pricilla:Pricilla I do not know how to do this problem. Don't know where to start. [(5)/(2x-8)]+[(3x^2+15)/(x^3-4x^2+5x-20)]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 Emily Ann:2x/x2-9 - 6/x2+x-12Answered by Penny Nom. A rational arithmetic expression 2005-09-14 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)/2nAnswered 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. Rational expressions 2003-01-22 From A student: // = the main fraction line 1.) a+1/a-1 + a-1/a+1 // a+1/a-1 - a-1/a+1 2.) 2/a(squared)-3a+2 + 2/a(squared)-a-2 // 2/a(squared)-1 + 2/ a(squared)+4a+3 Answered by Penny Nom. Rational expressions 2002-10-03 From Ashley:1/x(squared) + 5/xyAnswered by Penny Nom. Adding and subtracting rational expressions 2001-05-03 From Donna:Adding and subtracting Rational expressions. I am in grade 10 and I am a student here is an example of the questions: 1/(x+1) - 1/(x-1) = ? Answered by Penny Nom.
