A) \[2xy2=0\]
B) \[3x2y=0\]
C) \[2x3y+10=0\]
D) \[x2y+8=0\]
Correct Answer: A
Solution :
Let us Suppose equation of hyperbola is \[\frac{{{x}^{2}}}{{{a}^{2}}}-\frac{{{y}^{2}}}{{{b}^{2}}}=1\] \[e=2\Rightarrow {{b}^{2}}=3{{a}^{2}}\] passing through\[(4,6)\Rightarrow {{a}^{2}}=4,{{b}^{2}}=12\] \[\Rightarrow \]equation of tangent \[x-\frac{y}{2}=1\]\[\Rightarrow \]\[2x-y-2=0\]You need to login to perform this action.
