1.  Complete the square on each expression by stating the value of k.  Then factor the resulting perfect-square trinomial.

a)  xblank squared+ 2x + k                                          b)  xblank squared- 6x + k

c)  xblank squared- 3x + k                                           d)  xblank squared + 4 over 3x + k

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

xblank squared+ 2x -3 = 0

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

xblank squared - 4x + 8 = 0

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

2xblank squared - 3x - 1 = 0

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

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