Simplifying EquationsDate: 11/7/95 at 17:22:44 From: Anonymous Subject: algebra Question: 4ax+2a-4b -3ax-bx-a+3b ______________________ + __________________________ 2 2 2 2 ax -bx +3ax -3bx +2a -2b ax - bx +3ax -3bx +2a -2b Date: 11/12/95 at 15:33:22 From: Doctor Ethan Subject: Re: algebra Hey Deborah, If I understood your question correctly, then the denominators are the same so we can just add the tops together. 4ax + 2a - 4b - 3ax - bx - a + 3b = ax - bx + a - b And the bottom is the same. Now things get a little harder but here is what I recognized. On the bottom and the top we have a lot of a-b type patterns, so let's factor out an a-b on both the top and the bottom. so we have: (a-b)(x+1) ------------- (a-b)(x^2 + 3x + 2) See if you can work it from there. -Doctor Ethan, The Geometry Forum |
