Q.36
Correct Answer is:D
Solution Explain:
Since, p(x) = 0 is a quadratic equation with real coefficients having purely imaginary roots
Therefore p(x) = ax2 + b where a and b are of same sign
Now p(p(x)) = 0 ⇒ a(ax2 + b)2 + b = 0
But if x is purely real or purely imaginary then x2 is purely real
So, (ax2 + b)2 is purely real and greater than or equal to zero
⇒ p(p(x)) = a(ax2 + b)2 + b can never be zero
[as a and b are of same sign and b ≠ 0]
⇒ p(p(x)) = 0 can have only complex roots
