How to simplify: x^2 - 49 / x^2 - 14 + 49
This is what I have so far:
x^2 - 49 = (x + 7) (x - 7)

x^2 - 14 + 49 = x^2 + 35
x^2 + 35 = ?? It's not a perfect square, so I'm not sure what to do from here.

raden · Answer

i think the denominator is  x^2 - 14x + 49

raden · Answer

and that is can be factored  x^2 - 14 + 49  = (x-7)(x-7)
now, cancel out the similar terms in numerator and the denominator

There would only leave (x+7)

anonymous · Answer

And you are right about the denominator, sorry.
