Let the new origin be (h, k) = (1, 1)
Then, the transformation formula become:
x = X + 1 and y = Y + 1
Substituting the value of x and y in the given equation, we get
x2 + xy – 3x – y + 2 = 0
Thus,
(X + 1)2 + (X + 1)(Y + 1) – 3(X + 1) – (Y + 1) + 2 = 0
⇒ (X2 + 1 + 2X) + XY + X + Y + 1 – 3X – 3 – Y – 1 + 2 = 0
⇒ X2 + 1 + 2X + XY – 2X – 1 = 0
⇒ X2 + XY = 0
Hence, the transformed equation is X2 + XY = 0
