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
Hello 200001 Originally Posted by 200001 Start of problem at the top I believe i have done it right but it doesnt seem to factorise Do i need to run it from the quadratic equation? You have a sign wrong in the third line of your solution. It should be: Now . So the only valid root is: Grandad
