`2(x+y)^2-9(x+y)-5`

Find the square root of the expression (4x^2)/(y^2)+(20x)/(y)+13-(30y)/(x)+(9y^2)/(x^2)- (2x)/(y)+5-(3y)/(x) .

Area of the equilateral triangle inscribed in circle x^2+y^2 -7x+ 9y+5 =0 is:

If one end of a diameter of the circle 3x^(2) + 3y^(2) - 9 x + 6y + 5 = 0 is (1 ,2) then the other end is _

If one end of a diameter of the circle 3x^(2)+3y^(2)-9x+6y+5=0 is (1,2), then the other end is

If one end of a diameter of the circle 3x^(2)+3y^(2)-9x+6y+5=0 is (1, 2), then the other end is
