    1. Express \(x ^ { 2 } - 3 x + 5\) in the form \(( x - p ) ^ { 2 } + q\).
    2. Hence write down the equation of the line of symmetry of the curve with equation \(y = x ^ { 2 } - 3 x + 5\).
  1. The curve \(C\) with equation \(y = x ^ { 2 } - 3 x + 5\) and the straight line \(y = x + 5\) intersect at the point \(A ( 0,5 )\) and at the point \(B\), as shown in the diagram below.

    1. Find the coordinates of the point \(B\).
    2. Find \(\int \left( x ^ { 2 } - 3 x + 5 \right) \mathrm { d } x\).
    3. Find the area of the shaded region \(R\) bounded by the curve \(C\) and the line segment \(A B\).
