 x2 − y2 − 2x +2y = 0

बेरीज

उत्तर

 Substituting \[x = X + 1, y = Y + 1\] in the given equation, we get:
\[\left( X + 1 \right)^2 - \left( Y + 1 \right)^2 - 2\left( X + 1 \right) + 2\left( Y + 1 \right) = 0\]
\[ \Rightarrow X^2 + 2X + 1 - Y^2 - 2Y - 1 - 2X - 2 + 2Y + 2 = 0\]
\[ \Rightarrow X^2 - Y^2 = 0\]
Hence, the transformed equation is \[x^2 - y^2 = 0\]
