When the origin is shifted to the point (2,3) and then the coordinate axes are rotated through and angle (pi)/(3) in the counter clockwise sense, then the transformed equation of 3x^(2)+2xy+3y^(2)-18x-22y+50=0 is

Answer»

`3x^(2)+3Y^(2)-1=0`
`(6+sqrt(3))X^(2)-2XY+(6-sqrt(3))y^(2)-2=0`
`4X^(2)+2y^(2)-1=0`
`(6-sqrt(3))x^(2)+(6+sqrt(3))y^2+2xy=0`
