Question

Hello all, I would like some confirmation on a limits question.

The limit is as h --> 0,
[sqrt [73-5(x+h)] - sqrt (73-5x)]/h

I multiplied by the conjugate of the numerator and reduced everything down to this final answer:

[(-5)sqrt(73-5x)]/2

Is this correct?
should have been

-5 / ( 2√(73-5x) )

perhaps you just had a typo, check your work
