Hey guys
I have a Tutorial that I need to hand in , in 2 weeks but I am stuck with the following problem:
The question Is: "question.jpg"
The answer according to the notes the lecturer gave us is: 2-2u-9u^2.
When I do the math(see atttached document: "workings.jpg" My answer differ slightly and I can not see the problem in my workings, so hoping you guys can maybe spot a problem or if not maybe the answers he gave us is not correct.(even though I asked him and he could not give me a 100% on a yes or no).
