C) 4
D) 1
Correct Answer: B
Solution :
\[1\times 2\times 2+2\times \left( \frac{-5}{2} \right)\times \frac{3}{2}\times \left( \frac{-\lambda }{2} \right)-1\times \frac{25}{4}-2\times \frac{9}{4}-2\frac{{{\lambda }^{2}}}{4}=0\] \[\Rightarrow \lambda =3,\,\frac{9}{2}\].You need to login to perform this action.
