A) 5
B) 4
C) ?5
D) None of these
Correct Answer: C
Solution :
Since the general equation of second degree represents a rectangular hyperbola, if \[\Delta \ne 0,\,\,{{h}^{2}}>ab\] and coefficient of \[{{x}^{2}}+\]coefficient of\[{{y}^{2}}=0\]. Therefore the given equation represents a rectangular hyperbola, if \[\lambda +5=0\] i.e., \[\,\lambda =-5\].You need to login to perform this action.
