Final answer:
The given equation can be rearranged to the standard form of the ellipse equation.
Step-by-step explanation:
The given equation can be rearranged to the standard form of the ellipse equation by multiplying both sides by the denominator:
-1(x²+y²+1) + 2x(x-2y) = 0
Expanding and rearranging terms:
-x²-y²-x+4xy=0
Now we can see that the equation is:
x² - 4xy + y² + x - 1 = 0
Thus, the equation is in the standard form of the ellipse equation.
