उत्तर

 Substituting \[x = X + 1, y = Y + 1\] in the given equation, we get:
\[\left( X + 1 \right)^2 + \left( X + 1 \right)\left( Y + 1 \right) - 3\left( X + 1 \right) - \left( Y + 1 \right) + 2 = 0\]
\[ \Rightarrow X^2 + 2X + 1 + XY + X + Y + 1 - 3X - 3 - Y - 1 + 2 = 0\]
\[ \Rightarrow X^2 + XY = 0\]
Hence, the transformed equation is \[x^2 + xy = 0\]
