The equation of the pair of asymptotes of the hyperbola $\frac{(x-3)^2}{3}-\frac{(y-2)^2}{2}=1$ is

The equation of the pair of asymptotes of the hyperbola $\frac{(x-3)^2}{3}-\frac{(y-2)^2}{2}=1$ is
  1. $2 x^2-3 y^2-12 x+12 y-6=0$
  2. $2 x^2-3 y^2-12 x+12 y+8=0$
  3. $2 x^2-3 y^2-12 x+12 y-8=0$
  4. $2 x^2-3 y^2-12 x+12 y+6=0$

Solution

Equation of hyperbola is $ \begin{aligned} & \frac{(x-3)^2}{3}-\frac{(y-2)^2}{2}=1 \\ & \Rightarrow 2\left(x^2+9-6 x\right)-3\left(y^2+4-4 y\right)=6 \\ & \Rightarrow 2 x^2-3 y^2-12 x+12 y+6=6 \\ & \Rightarrow 2 x^2-3 y^2-12 x+12 y=0 \end{aligned} $ Pair of asymptotes of the curve differs by the constant only. $\therefore$ Equation of pair of asymptotes is : $ 2 x^2-3 y^2-12 x+12 y+\lambda=0 $ which represents a pair of straight line if $ \Delta=a b c+2 f g h-a f^2-b g^2-c h^2=0 $ where $\mathrm{a}=2, \mathrm{~b}=-3, \mathrm{~h}=0, \mathrm{~g}=-6$ $ \mathrm{f}=6 \mathrm{c}=\lambda $ Then, we have : $ \begin{aligned} & 2 \times(-3) \lambda+2 \times 6 \times(-6) \times 0-2(+6)^2-(-3)(-6)^2-\lambda \\ & \times 0=0 \Rightarrow \lambda=6 \end{aligned} $ Putting the value of $\lambda$ in eq ${ }^{\mathrm{n}}$ (i), we get $ 2 x^2-3 y^2-12 x+12 y+6=0 $
