Question

polynomial help please!
x+3/x^3-2x^2-22x+33

Answer 1

\[\frac{ x^{3}-2^{2}-22x+33 }{ x+3 }\]

Answer 2

Are you dividing or just simplifying?

Answer 3

the bottom becomes x-3?

Answer 4

dividing

Answer 5

I really do not remember this. Sorry @mocham bump this when you can.

Answer 6

I use wolframalpha for problems like these :D this is what I got: http://www.wolframalpha.com/input/?i=x%2B3%2Fx%5E3-2x%5E2-22x%2B33 ^_^

Answer 7

How's your synthetic division?

Answer 8

oh wait, it would be http://www.wolframalpha.com/input/?i=%28x%5E3%E2%88%922%5E2%E2%88%9222x%2B33%29+%2F+%28x%2B3%29 ^_^

Answer 9

do I have to change the x+3 to x-3? I have to use long division

Answer 10

Don't change ANYTHING for "Long" division. Just find the right factors at each stage.

Answer 11

i need some help with the first steps and factoring

Answer 12

I get the idea ... I know its already in form because of the exponents and im thinking that I have to figure out how many times x+3 goes into \[x^{3}\] ?

Answer 13

x^3

Answer 14

You are not familiar with synthetic division? It will be much easier.

But if you are doing long division, figure out how many times x goes into x^3.

Answer 15

im learning synthetic next but for some reason our professor wants to torture us and make us do lots of long division first ...

Answer 16

x goes into x - 1 times so it will be x?

Answer 17

so it would be x^4?

Answer 18

No. When you divide, the polynomial degree will go down. Not increase from x^3 to x^4.

Answer 19

x^2 - 6x?

Answer 20

no ... its not 6x ...

Answer 21

=/

Answer 22

x goes into x^3 x^2 times. Multiply x^2 by x and then by 3 and write it underneath. Subtract ....

Answer 23

that's it?

Answer 24

Then on to the next term, then the next, .. until you are done.

Answer 25

gre

Answer 26
