Lös (x+6)^2/16+(y+2)^2/81=1

$$\frac { ( x + 6 ) ^ { 2 } } { 16 } + \frac { ( y + 2 ) ^ { 2 } } { 81 } = 1$$

Lös ut x (complex solution)

$$x=-\frac{4i\sqrt{y-7}\sqrt{y+11}}{9}-6$$

$$x=\frac{4i\sqrt{y-7}\sqrt{y+11}}{9}-6$$

Lös ut y (complex solution)

$$y=-\frac{9i\sqrt{x+2}\sqrt{x+10}}{4}-2$$

$$y=\frac{9i\sqrt{x+2}\sqrt{x+10}}{4}-2$$

Lös ut x

$$x=\frac{2\left(-2\sqrt{\left(7-y\right)\left(y+11\right)}-27\right)}{9}$$

$$x=\frac{2\left(2\sqrt{\left(7-y\right)\left(y+11\right)}-27\right)}{9}\text{, }y\geq -11\text{ and }y\leq 7$$

Lös ut y

$$y=\frac{-9\sqrt{-\left(x+2\right)\left(x+10\right)}-8}{4}$$

$$y=\frac{9\sqrt{-\left(x+2\right)\left(x+10\right)}-8}{4}\text{, }x\geq -10\text{ and }x\leq -2$$
