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

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 :)
