If f(x)= x²-x
Then f(x+1)-f(x) =!?
~~~~~~~~~~~~~~~~~~~~~~~ 

If f(x)= x%5E2-x  then  f(x+1) = %28x%2B1%29%5E2+-+%28x%2B1%29.  


Then f(x+1)-f(x) = %28x%2B1%29%5E2+-+%28x%2B1%29 - %28x%5E2-x%29.


Now open the parentheses and simplify.


Keep in mind that you got the BEST possible answer.


The rest is on your own.
