Mark scheme
Marking points from the official mark scheme (May/June 2016). The mark or mark type is shown in brackets.
- [3*] (a) (3+4t)/(t-1) oe C2 for (7)/(t-1) or (3-4t)/(t-1)
- OR M1 for t(p – 4) = p + 3 or pt – 4t = p + 3
- AND M1 for isolating p terms after fraction eliminated e.g. pt - p = 3 + 4t or p(t − 1) = 3 + 4t
- [3*] (b) (2x-1)/(x-5) final answer B1 for (2x + 1)(2x – 1) seen AND B1 for (2x + 1)(x – 5) seen
