Solve for X

Tidus, I'm in college as you can obviously tell in my sig.

Robot, the reason for writing x^0, cuz i'm afriad people might not follow that i put it in quadratic form.

And I'm going to write how to follow this...

Line 1->2: Long Division
Line 2->3: multiplied every element with (x-y)
Line 3->4: on the left side added; on the right side distribed
Line 4->5: put x on right side and use communitive property to group the first 2 terms
Line 5->6: subtracted y from both sides; x^0 = 1 so i multiply by 1, which doesn't change the answer; also reverse distrubted (is there a better way to say this?) x into 2y^2-x.
Line 6->7: Quadratic formula (Algebra I)
Line 7->8: distributed and simplified inside the root and the negative outside the root
Line 8->9: added

Oh if you guys need help with high school math up to about 2nd year college math(you only need math as an engineer or math major), i can TRY to help you. Being a nice guy and all...
