# Thread: How can i simplify this?

1. ## How can i simplify this?

If a and h are real numbers,

1. f(x) = 1_
x

f(a+h) - f(a)
h

= (1/a+h) - (1 / a)
h

is this correct, if so, can it be simplified?

2. Yes, and it can be simplified. What you need to do is add the fractions together and proceed from there.
