(A) Given the quadratic equation $x^2 + px + (1 - p) = 0$. Since $(1 - p)$ is a root,it must satisfy the equation: $(1 - p)^2 + p(1 - p) + (1 - p) = 0$ Factor out $(1 - p)$: $(1 - p) [(1 - p) + p + 1] = 0$ $(1 - p) [2] = 0$ This implies $1 - p = 0$,so $p = 1$. Substituting $p = 1$ into the original equation: $x^2 + (1)x + (1 - 1) = 0$ $x^2 + x = 0$ $x(x + 1) = 0$ Thus,the roots are $x = 0$ and $x = -1$.
