Find the equations of the asymptotes of the hyperbola 3x2+10xy+8y2+14x+22y+7=0

Open in App
Solution

Given, 3x2+10xy+8y2+14x+22y+7=0
standard form of hyperbola is
x2a2y2b2=1 Asymptotes:-
x2a2y2b2=0
So,
=3x2+10xy+8y2+14x+22y+10=0
This is pair of straight lines.
a=3,b=8,g=7,b=11,n=5,c=k
∣ ∣ahghbbgbc∣ ∣=0∣ ∣3575811711k∣ ∣=0
3(8k121)5(5k77)+7(5556)=0
24k36325k+3857=0
k370+385=0
k=15
Asymptotes are :-
3x2+10xy8y2+14x+22y+15=0
