Question 730768
Formula for difference quotient edited for grouping.


There are two terms in the expression to which to find the difference quotient.  The 2 is a separate term from the 3*sqrt(9x-7).  They are NOT connected except by addition of the two separate terms.


To begin with the difference quotient,
{{{((2+3sqrt(9(x+h)-7))-(2+3sqrt(9x-7)))/h}}}
