\[\frac{ x^2+6x-5 }{ x^2-25 }\]

Make factorización The first polinomial can be written as follows (x-5)(x-1)

OpenStudy (alex6799):

ok

OpenStudy (isaidavila):

The second can be written like that (x-5)(x+5)

OpenStudy (isaidavila):

So just simplify an you get the answer

OpenStudy (alex6799):

how would i simplify that?!

OpenStudy (isaidavila):

Ok (x-5)(x-1)/(x+5)(x-5) You can simplify x-5

OpenStudy (alex6799):

5

OpenStudy (isaidavila):

No just divide (x-5)/(x-5) is equal to.....

OpenStudy (alex6799):
