(sqrt(2)x-3y)^(2)

Expand each of the following (sqrt(2x)-3y)^(2)( ii) (2x-(1)/(3x))^(2)

The locus of the point P(x,y) satisfying the relation sqrt((x-3) ^(2) +(y-1)^(2))+ sqrt((x+3) ^(2) +(y-1)^(2))=6 is-

If 2sqrt(2)x^(3)-3sqrt(3)y^(3)=(sqrt(2)x-sqrt3y)(Ax^(2)+by^(2)+Cxy) . Then the value of A^(2) + B^(2) - C^(2) is :

| The eccentricity of the hyperbola |sqrt((x-3)^(2)+(y-2)^(2))-sqrt((x+1)^(2)+(y+1)^(2))|=1 is
