# How do I turn the equation of a rotated ellipse into its equation when not rotated?

So let's say I have the equation "4y^2+2xy+2x^2-8x=51". This is a rotated ellipse, so how can I find its equation when it is not rotated, however still has the same vertical and horizontal stretches? Thank you in advance.
