Will add more questions when workbook arrive:

1a) Find the set of values of x for which x(x – 5) < 14 (4 marks)

2) The equation x** ^{2}** + (k – 3)x – 4k has two
distinct reals roots

2a) show that k satisfies k** ^{2}** + 10k + 9
> 0 (3 marks)

2b) Hence find the set of possible values for k (4 marks)
