A) \[A+B=0\]
B) \[B+H=0\]
C) \[A+H=0\]
D) \[AH=-1\]
Correct Answer: C
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.
