Homework Help: Simplifying Rational Expressions

Posted by mike on Wednesday, May 16, 2007 at 8:58pm.

Alright I believe i got it right this tim(They should be typred out correctly).Can someone solve these for me
1.(4x-12)/4x
2.(d+7)/(d^2-49)
3.(t^2)-25/(t^2+t-20)
4.(2x^2+6x+4)/(4x^2-12x-16)
5.(6-y)/(y^2-2y-24)

We do not do your work for you.

Find the factors for the numerator and denomintor to find those that will cancel each other out. For example,

(t^2)-25/(t^2+t-20) = (t+5)(t-5)/(t+5)(t-4)

I hope this helps. Thanks for asking.
