Solution for y^2-xy-x^2=0 equation:


Simplifying
y2 + -1xy + -1x2 = 0

Reorder the terms:
-1xy + -1x2 + y2 = 0

Solving
-1xy + -1x2 + y2 = 0

Solving for variable 'x'.

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
xy + x2 + -1y2 = 0

Move the constant term to the right:

Add '-1y2' to each side of the equation.
xy + x2 + -1y2 + -1y2 = 0 + -1y2

Combine like terms: -1y2 + -1y2 = -2y2
xy + x2 + -2y2 = 0 + -1y2
Remove the zero:
xy + x2 + -2y2 = -1y2

The x term is xy.  Take half its coefficient (0.5y).
Square it (0.25y2) and add it to both sides.

Add '0.25y2' to each side of the equation.
y2 + x2 + -2y2 + 0.25y2 = -1y2 + 0.25y2

Reorder the terms:
x2 + y2 + -2y2 + 0.25y2 = -1y2 + 0.25y2

Combine like terms: y2 + -2y2 = -1y2
x2 + -1y2 + 0.25y2 = -1y2 + 0.25y2

Combine like terms: -1y2 + 0.25y2 = -0.75y2
x2 + -0.75y2 = -1y2 + 0.25y2

Combine like terms: -1y2 + 0.25y2 = -0.75y2
x2 + -0.75y2 = -0.75y2

Factor a perfect square on the left side:
(x + 0.5y)(x + 0.5y) = -0.75y2

Can't calculate square root of the right side.

The solution to this equation could not be determined.
