If the transformed equation of curve is 3x^(2) + xy - y^(2) - 7x + y + 7 = 0 when the axes are translated to the point (1,2) thenthe original equation of curve is

Answer»

`3x^(2) + xy - y^(2) + 15 x + 4y + 13 = 0`
`3x^(2) + xy - y^(2) - 15 x + 4y + 13 = 0`
`3x^(2) + xy + y^(2) - 15 x + 4y + 13 = 0`
`3x^(2) + xy - y^(2) - 15 x - 4y + 13 = 0`
