Question 25

A quadratic polynomial $p(x)$ with real coefficients and leading coefficient $1$ is called *disrespectful* if the equation $p(p(x))=0$ is satisfied by exactly three real numbers. Among all the disrespectful quadratic polynomials, there is a unique such polynomial $\tilde{p}(x)$ for which the sum of the roots is maximized. What is $\tilde{p}(1)?$
  1. $\dfrac{5}{16}$
  2. $\dfrac{1}{2}$
  3. $\dfrac{5}{8}$
  4. $1$
  5. $\dfrac{9}{8}$
