I'm new - very glad I found this. I have a prescribed textbook for my math course - in the back they only give you answers to the problems but do not show how they got the answer - so its difficult to trace your steps and see where you went wrong. Which explains me being stuck with these 3 problems.
I'll explain :
Long or synthetic division can be used for this one:
2x^4 - X^3 + 9x^2 divided by x^2 + 4
When I do the above one, I get to a point where I have powers that arent the same so I can't minus - all the ways I try it I either get stuck where I can't divide more or I get a wrong answer than that in the book - I'd like to see what answer some of you get, maybe the book is wrong. Please type our your steps - Im desperate to see where I go wrong.
Okay this one you have to use long division - again I get a horribly wrong answer if compared to the back of the book:
6x^3 + 2x^2 + 22x divided by 2x^2 + 5
The one below must be done using synthetic division - again my answer is wrong compared to the back of my textbook and I can't seem to understand why or how:
x^3 + 2x^2 + 2x + 1 divided by x + 2
I would appreciate your help a lot I'm either overlooking something or the book is wrong and Im very keen to find out which!
