How find this value for $b,c,d$ are real numbers. let $b,c,d$ are real numbers, find this value > $$\dfrac{b+c-2\dfrac{2bd-bc-cd}{b+d-2c}}{\left(\dfrac{2bd-bc-cd}{b+d-2c}\right)^2-bc}-\dfrac{d+\dfrac{4bd-cd-3bc}{b-4c+3d}-b-c}{bc-d\dfrac{4bd-cd-3bc}{b-4c+3d}}$$ Thank you

Since I am just a bit less lazy than you I typed this expression in Mathcad, chose “Symbolics/Simplify” and obtained 0. It is a pity – so much efforts for nothing.
