Consider the quadratic equation x²−(r+7)x+r+87=0 where r is a real number. This equation has two distinct real solutions x which are both negative exactly when p<r<q, for some real numbers p and q. What is the value of p²+q²?
Original LaTeX notation
Consider the quadratic equation $x^{2}-(r+7) x+r+87=0$ where $r$ is a real number. This equation has two distinct real solutions $x$ which are both negative exactly when $p<r<q$, for some real numbers $p$ and $q$. What is the value of $p^{2}+q^{2}$?
