Proper grouping symbols are important.
highlight%28%28f%28x%2Bh%29-f%28x%29%29%2Fh%29

Using your function,
(x^2-7x+4),

%28%28%28x%2Bh%29%5E2-7%28x%2Bh%29%2B4%29-%28x%5E2-7x%2B4%29%29%2Fh
%28x%5E2%2B2hx%2Bh%5E2-7x-7h%2B4-x%5E2%2B7x-4%29%2Fh
%282hx%2Bh%5E2-7h%29%2Fh
If nothing was missed, then obtain
highlight%282x%2Bh-7%29
