The condition that the equation $a x to the power of 2 end exponent plus 2 h x y plus b y to the power of 2 end exponent plus 2 g x plus 2 f y plus c equals 0$ can take the form $a x squared plus 2 h x y plus b y squared equals 0$ when shifting the origin is

When the roots are equal and real, then the discriminant value of the the quadratic equation becomes 0.

The transformed equation of $14 x to the power of 2 end exponent minus 4 x y plus 11 y to the power of 2 end exponent minus 36 x plus 48 y plus 41 equals 0$ when the axes are translated to (1, –2) is

shifting of origin is done when the aes are shifted parallely to a different location on the cartesian plane.
this results in change of coordinates as: x=x'+h and y=y'+k
where h,k are the new origin.
