ugent solving volume
i have an equation, which solving for volume
EQUATION: [P+(a/V^2)]*(V-b) = RT
solve for V.
First multiply out the bracket:

(PV-Pb-RT) + a/V - ab/V^2 = 0.
Multiply through by V^2:
(PV-Pb-RT)V^2 + aV - ab = 0,
which is a quadratic in V^2, so you can now use the quadratic
formula to find V.
