\section*{Solutions relying on calculator technology are not acceptable.} The equation $$4 ( p - 2 x ) = \frac { 12 + 15 p } { x + p } \quad x \neq - p$$ where \(p\) is a constant, has two distinct real roots.
  1. Show that $$3 p ^ { 2 } - 10 p - 8 > 0$$
  2. Hence, using algebra, find the range of possible values of \(p\)
