Question

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

$14 x^{2} + 4 x y - 11 y^{2} = 25$
$14 x^{2} - 4 x y + 11 y^{2} = 25$
$14 x^{2} + 4 x y + 11 y^{2} = 25$
none of these

hint Hint:

replace the values of new x and y coordinates and solve.

The correct answer is: $14 x to the power of 2 end exponent minus 4 x y plus 11 y to the power of 2 end exponent equals 25$

$14 x to the power of 2 end exponent minus 4 x y plus 11 y to the power of 2 end exponent equals 25$

when the origin is shifted to (1,-2), we get
x= x’ + 1 and y=y’-2
replacing this in the equation, we get
14x’²+11y’² -4x’y’-25=0

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.
