%286x%5E2%2B13x%2B6%29%2F%286-5x-6x%5E2%29
Generally easier when the coefficient of x^2 is positive, factor out -1 and rearrange to:
%286x%5E2%2B13x%2B6%29%2F%28-1%286x%5E2%2B5x-6%29%29
Factor
%28%283x%2B2%29%282x%2B3%29%29%2F%28-1%28%283x-2%29%282x%2B3%29%29%29
the -1 makes the expression negative
-%28%283x%2B2%29%282x%2B3%29%29%2F%28%283x-2%29%282x%2B3%29%29
(2x+3) cancels, leaving:
-%28%283x%2B2%29%29%2F%28%283x-2%29%29
