Simplifying 0 = X2 + 4xy + -4y2 Solving 0 = X2 + 4xy + -4y2 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-1X2' to each side of the equation. 0 + -1X2 = X2 + 4xy + -1X2 + -4y2 Remove the zero: -1X2 = X2 + 4xy + -1X2 + -4y2 Reorder the terms: -1X2 = X2 + -1X2 + 4xy + -4y2 Combine like terms: X2 + -1X2 = 0 -1X2 = 0 + 4xy + -4y2 -1X2 = 4xy + -4y2 Divide each side by '-1'. X2 = -4xy + 4y2 Simplifying X2 = -4xy + 4y2 Reorder the terms: X2 + 4xy + -4y2 = -4xy + 4xy + 4y2 + -4y2 Combine like terms: -4xy + 4xy = 0 X2 + 4xy + -4y2 = 0 + 4y2 + -4y2 X2 + 4xy + -4y2 = 4y2 + -4y2 Combine like terms: 4y2 + -4y2 = 0 X2 + 4xy + -4y2 = 0 The solution to this equation could not be determined.
