Yes I can now see I am wrong.

I took a and b to be pronumerals when they are cleaarly marked as directional vectors.

If a and b were ordinary pronumerals then the question would be nonsense but as directional vectors (as is stated in the question) it is my answer that is nonsense. Sorry all.

**Thanks Tiggsy and Heureka. **

Also CPhill found the answer as a video clip on a seperate site.

This is the site

http://www.onlinemathlearning.com/edexcel-gcse-specimen-p1-higher.html

Scroll down till you find this heading

*"Edexcel GCSE 9 - 1 Specimen Paper 1 (No Calculator) Solutions for Questions 8 - 23"*

Underneath it says "Show step by step solutions"

Click on that and the video will display. This is question 22. The answer for it begins at 55:27

You can forward the clip to bigin at that point.

**Thanks Chris for finding this resource for us :)**
