/ %284x-1%29+%2F+%283x%2B1%29
Take out (x-4y) as a factor, top and bottom
%28%28x-4y%29%283x%5E2-20x%2B25%29%29%2F+%28%284y-x%29%283x%5E2-14x-5%29%29+*+%283x%2B1%29%2F%284x-1%29+
cancel the common factors on top and bottom, and factorise the quadratic expressions
+-%283x-5%29%28x-5%29%2F%283x%2B1%29%28x-5%29%2A%283x%2B1%29%2F%284x-1%29%29+
cancel the common factors on top and bottom,
