subtract, simplfy by removing a factor of 1 when possible.
19dc/d^2-c^2 - d-c/d+c

You must mean ....
19cd/(d^2 - c^2) - (d-c)/(d+c)
then ...
= 19cd/((d+c)(d-c) - (d-c)/(d+c)
LCD is (d+c)(d-c)
= ( 19cd - (d-c)(d+c) )/((d+c)(d-c) )
= (c^2 + 19cd - d^2)/(d^2 - c^2)
not much of a simplication.
Confirm if my assumption of the question was correct.
