Divide. Use synthetic division, if possible.
(x^4+6x^3-x^2-5x+1)/(x-2)
(x^3+9x^2-5x+11)/(x^2+2)

\[\frac{(x^4+6x^3-x^2-5x+1)}{(x-2)}\]
First you would want to factor out from the first 2 terms such that x-2 would be left out,
for that we can write
\[6x^3=8x^3-2x^3\]
\[\implies \frac{(x^4-2x^3+8x^3-x^2-5x+1)}{(x-2)}\]
Take out
x cube\[\frac{(x^3(x-2)+8x^3-x^2-5x+1)}{(x-2)}\]
Now try to write
-x^2 as something so that when u take out 8x^2 common from 8x^3 and -x^2 you would be left with x-2 just like we did with first 2 terms

Isn't synthetic division where you only use the coefficients? i guess im having more trouble doing with the second one-dividing the x^2+2

- anonymous

I don't know what's "synthetic" division, but u can also simply just divide it, but I prefer to take out factors like that, I find it simpler

Have u done the first one?

- anonymous

you know it would be so much easier to do it on calcilator

- anonymous

i think synthetic division is the one where you have the divisor boxed in the top left

- anonymous

i forget if u box a positive 2 or a negative 2

Sorry I've no idea about this method, but you can simply use long division or rewrite terms and take out factors, it's much simpler to just do long division honestly

- anonymous

thats for the first one

- anonymous

i think the answer needs to be a number not a graph

- anonymous

are you sure

- anonymous

its ok thanks for trying

- anonymous

ya it should be a number

- anonymous

oops

- anonymous

i got the first one, just need the second

- Nnesha

right synthetic where you just need coefficients
and set the divisor equal to zero x-2=0 solve for x(add 2 both sides )x=2 |dw:1439293979673:dw|
drop down the leading coefficient and then multiply by x value which is 2
write your answer above the line and combine that with 2nd term coefficient
2 times 1=2
6+2=8

- Nnesha

apply long division method for 2nd one
bec highest degree is 2
synethic division method is best for highest degree o one
like x+2
x+4
