The expression f(x)=ax^3-(a+3b)x^2+2bx+c is exactly divisible by x^2-2x. When f(x) is divided by x-1, the remainder is 8 more than when it is divided by x+1. Factorise f(x) completely. Find the range of values of x for which f(x)<0.

How do you get rid of c? It doesn't allow me to do simultaneous eqn. if you factorise x^2-2x=x(x-2), does it mean if you let x=0, then f(0)=c, c=0"?

I have been told that I have a large adenoma in the liver. Could this be the cause of two large rectal bleeds? Colonoscopies (2) both normal? Very tired all the time everything an effort. Can it be cured? Is it dangerous? ultrasound and CT scans show a mass which is suspected to be an adenoma now awaiting MRI but not really sure why? No-one is explaining anything and a lot of misdiagnosis so far. Am I able to ask to be transferred to another doctor in another hospital? Do not feel I am being taken too seriously no-one seems to feel that an explanation is called for! Consultant never reads my notes before I go in to see him and often is looking at tests conducted months ago. I would like to see someone else am I able to do this or am I stuck with this very rude man who has so little regard for his patients? I have no idea what is really going on and no-one will answer my questions. I am not a fool and I am very aware that something very wrong is going on not sure how wrong?
