Question 981784
To show the quotient correctly, you MUST properly group the numerator.  The forward slash character alone does not act as a grouping symbol.


Be careful what you express!
{{{f(x)=x^2-2}}}  is your function given.
{{{f(x)<>(((x^2-2)+h)-x^2-2)/h}}}.


You want to use your algebra skills to form the difference quotient for your function.


{{{(((x+h)^2-2)-(x^2-2))/h}}}


This need to be simplified.

Be sure you understand {{{f(x)<>(((x+h)^2-2)-(x^2-2))/h}}}.
