Hi!

In physics I derived the following expression, and I have no idea where to start simplifying it:

$\displaystyle R_v = \frac{\frac{R_1 V_x}{E-V_x}R_2}{R_2 - \frac{R_1V_x}{E-V_x}}$

The lot in brackets is the same expression, so my hunch tells me this could be written much simpler? Or could it?
