If one root of the equation

x^2-\lambda x+12=0

is even prime while

x^2+\lambda x+\mu=0

has equal roots, then

\mu

View answer and explanation

Correct option: B

Option B (16) is correct because the value of

\mu

is found by first determining

\lambda

from the first equation and then using the condition for equal roots in the second equation.
