this is for working out partial pressures at equilibrium in chemistry i have this equation and am stuck on how to work it out.

$50 = \frac{2p^2}{p^2-0.5p+0.04}$
can someone please explain how to find p. I know how to work out quadratics im just lost of how to do it as a frac.

You can rewrite the above equation as
$50(p^2- 0.5p+0.04) = 2p^2$
Now simplify and solve the quadratic equation.
