Question 930352
{{{log((x^2+2x-3)/(x^2-4))-log((x^2+7x+6)/(x+2))}}}


{{{log(((x+3)(x-1))/((x-2)(x+2)))-log(((x+6)(x+1))/(x+2))}}}


{{{log(((((x+3)(x-1))/((x-2)cross((x+2))))/(((x+6)(x+1))/cross((x+2)))))}}}


{{{log(((((x+3)(x-1))/((x-2)))/(((x+6)(x+1))/1)))}}}


{{{log((((x+3)(x-1))/((x-2)(x+6)(x+1)))))}}}
