Homework Help: Simplifying Rational Expressions

Posted by mike on Wednesday, May 16, 2007 at 9:16pm.

Can someone slove these for me
2.(d+7)/(d^2-49 )

all you have to do is reduce like #1


cross out the 4x b/c it's on the top and bottom which leaves just -12 on the top

You can't do that!!!

That is like saying (4 + 5)/4 = 5

= 4(x-3)/(4x)
= (x-3)/x
