I believe i have done it right but it doesnt seem to factorise

Do i need to run it from the quadratic equation?

Yes, thats where i went with it but this is from a book that isnt driven at any equations that wont factorise and the level its picthed at would not go into that depth.

I had the same answer yet though I had gone wrong somewhere (Headbang) - Feb 14th 2010, 12:55 AMGrandad
