I get this (2x)(x+7) - (x) (3+3) = (y^2 -1) then I get (2x^2 +14 x)(x-3x) = (y^2 -1) but then I keep getting zero on both side???? Help please!!!]]>http://www.mathisfunforum.com/profile.php?id=24692006-05-05T08:48:18Zhttp://www.mathisfunforum.com/viewtopic.php?pid=34284#p342841. 8/(x+4) +1 = 5x/(x^2-2x-24)
2. 2x(x+3) - x/(x+7) = (x^2-1)/(x^2+10x+21)
Any one able to show me where to start after figuring out the LDC would be my hero for the day!
The LDC for 1 is (x-6)(x+4) and far 2 it's (x+3)(x+7) correct?
