View the equation as a quadratic ##ay^2+by+c=0## with ##a=3, b=-2x, c=4x^2##, that is if you want to find ##y=f(x)##.
if you want to find ##x=f(y)## then view it as a quadratic ##ax^2+bx+c=0## with ##a=4,b=-2y, c=3y^2##.
 
What do I do with the 2 at the end of the original equation?

Ah yes sorry, I thought it was =0, just incorporate 2 inside c, so ##c=4x^2-2## (or ##c=3y^2-2##)
 
Ah! Well that's going to be fun! Thank you so much!
