The question, in short
Points O, P and Q have position vectors OP = a − 2b and OQ = 4a + 4b. Find vector PQ in its simplest form in terms of a and b.
Summarised in our own words. Use the official paper for the exact wording and any diagrams.
Solution · 2 marks
- 1→PQ = →PO + →OQ = −(a − 2b) + (4a + 4b)
- 2= −a + 2b + 4a + 4b
- 3= 3a + 6b
Answer3a + 6b
