can x^2+3x-28/x^2-11x+28 be simplified anymore do the -28 and +28 cancel out in this case?

Question

can x^2+3x-28/x^2-11x+28  be simplified anymore do the -28 and +28 cancel out in this case?

anonymous · Answer

this can be factored to (x+7)(x-4)/(x-7)(x-4)
the factors of (x-4) will cancel leaving you with
(x+7)/(x-7)

anonymous · Answer

the problem was simplify (x+7)(x+4)/(x-8)((x-9)

anonymous · Answer

im just supposed to simplify so i dont multiply the numerators and denominators?

anonymous · Answer

(x-9)(x-8) = x^2 - 17x +72, how did you get x^2 - 11x +28 in the denominator?

anonymous · Answer

oh i got x^2-16x+28 in the denominator

anonymous · Answer

so the original problem was simplify (x+7)(x+4)/(x-9)(x-8)?

anonymous · Answer

yes

anonymous · Answer

wait (x+7)(x-4)/(x-7)(x-4)

anonymous · Answer

i got x^2+3x-28/x^2-11x+28

anonymous · Answer

ok if you are sure that the original problem was to simplify (x+7)(x-4) /(x-7)(x-4) you can cancel out a factor of (x-4) from both the numerator and denominator.  

This leaves you with (x+7)/(x-7) as your final answer

ok thanks

anonymous · Answer

no problem :)
