c)  x- 3x + k                                           d)  x + x + k

2.  Solve this question by completing the square.  Simplify the solution.

x+ 2x -3 = 0

3.  Solve this question by completing the square.  Simplify the solution.

x - 4x + 8 = 0

4.  Solve this question by completing the square.  Simplify the solution.

2x - 3x - 1 = 0

5.  Solve this question by completing the square.  Simplify the solution.  Note, you will first have to change this equation to ax + bx + c = 0, then complete the square.

(x + 2)(x - 1) = 6
