A) one
B) two
C) three
D) infinite
Correct Answer: B
Solution :
We have the equation\[A{{x}^{2}}+2Bxy+H{{y}^{2}}=0\] ...(i) Since, the lines represented by Eq. (i) are perpendicular, therefore coefficient of\[{{x}^{2}}+\]coefficient of \[{{y}^{2}}=0\] \[\Rightarrow \] \[A+H=0\]which is the required condition.You need to login to perform this action.
