9 The quadratic equation \(2 x ^ { 2 } + p x + 3 = 0\) has two roots, \(\alpha\) and \(\beta\), where \(\alpha > \beta\). 9
    1. Write down the value of \(\alpha \beta\). 9
  1. (ii) Express \(\alpha + \beta\) in terms of \(p\). 9
  2. Hence find \(( \alpha - \beta ) ^ { 2 }\) in terms of \(p\).
    9
  3. Hence find, in terms of \(p\), a quadratic equation with roots \(\alpha - 1\) and \(\beta + 1\)
