Accepted Answer

\frac{-R_2R_3R_f + R_1R_4R_f}{R_1R_3R_4 + R_2R_3R_4 + R_1R_2(R_3 + R_4)}

Answer

-\frac{2R_f}{R_1R_3R_4 + R_2R_3R_4 + R_1R_2(R_3 + R_4)}

Answer

\frac{R_2R_3R_f + R_1R_4R_f}{R_1R_2R_3 + R_2R_3R_4 + R_1R_3R_4}

Answer

-\frac{R_2R_3R_f + R_1R_4R_f}{R_1R_3R_4 + R_2R_3R_4 + R_1R_2R_3}

Answer

-\frac{R_1R_3R_f + R_1R_4R_f}{R_1R_3R_4 + R_2R_3R_4 + R_1R_2(R_3 + R_4)}
