Homework Help: Can someone please help

Posted by Jojo on Wednesday, May 23, 2007 at 9:55am.

Can someone show me how to find the sum of this equation and put it in it's simpliest form?
(x^2)/(x^2-25)+(7x+10)/(x^2-25)

They have a common denominator:
x^2-25 which can factor to (x+5)(x-5)

The numerator will add to
x^2+7x +10 which can factor to
(x+5)(x+2)

Notice the numerator and denominator have a common factor which will divid out.
