$(\frac{ x+h }{ x+h+1 }-\frac{x}{x+h})*1/h$ I've plugged it into the equation, but can't seem to get anywhere with the algebra part

2. hartnn

because its x+1 in 2nd term

3. hartnn

the algebra part is very easy (x+h)(x+1) - x(x+h+1) simply turns out to be h

4. anonymous

ahh wow

5. anonymous

6. anonymous

think I need to figure out a way to focus better
