Convert the equation to the standard form for a hyperbola by completing the square on x and y. x2 - y2 + 6x - 4y + 4 = 0?
(x + 3)2 + (y + 2)2 = 1


(x + 3)2 - (y + 2)2 = 1


(y + 3)2- (x + 2)2 = 1


(y+3)^2/16 − (x+2)^2/36 = 1

Respuesta :

x² + 6x + ____ - (y² + 4y + ____ ) = -4 + ____ + ____
x² + 6x + 9      -  (y² + 4y + 4 )       = -4 +   9     +    -4
   (x + 3)²        -      (y + 2)²            = 1

Answer: B
