Help Please

hello guys, I got this number on my assignment but i just can't make v the subject of the formula.The number is k/27=v^2/(1-v). I'm asked to make v the subject of the formula but I just can't do it. Some help would be appreciated.
cheers.

Do you mean solve the equation for v? If so, just multiply both sides by (1-v) and collect terms. You end up with a quadratic in v that can be solved using the quadratic formula:

x = ( -b +/- sqrt(b^2 - 4ac) )/(2a)
