1.   Expand:
   (a).   ( a + 3 )2

   (b).   ( a - 5 )2

   (c).   ( 2c + 3d ) ( 3c + 4d )
   (d).   ( 2a + 5b ) ( 2a - 5b )
   (e).   5a ( b + c) + 3b ( a - b )

2.   Factorise:
   (a).      x² –  4x  +   4 =
   (b).   25x – 10y + 50 =
   (c).     x² – 16 =

3.   Solve the equation ( x + 4 ) ( x - 11 ) = 0 !

4.   Fill up the missing words:
   (a).   The equation of the y-axis is ____________
   (b).   The line of ______________ of the graph of the quadratic
            equation is passing through its maximum or minimum points.
