Text Solution
Verified by ExpertsD
To determine the set of real values of 
for which the vectors 
and 
are perpendicular, we use the condition that their dot product must be zero.
Let 
and 
.
Calculate the dot product 
:
For 
, we have:
To find the solutions to this quadratic equation, use the quadratic formula 
, where 
, and 
:
Since 
is imaginary, the quadratic equation has no real roots. Therefore, there are no real values of 
for which 
and 
are perpendicular.
Hence, the correct answer is
