Answer & Solution

Correct Answer

(B) \(x^2-2 y^2+3 x y+4 x-y-20=0\)

Step-by-step Solution

Detailed explanation

It is given that the origin is shifted to point \((2,3)\) and due to that the transformed equation of the curve is, \(x^2+3 x y-2 y^2+17 x-7 y-11=0\), to get the original equation of curve, replace \((x, y)\) by \((x-2, y-3)\), so by doing this. we get,…
