How do you divide polynomials using long division
levacccp [35]
This is a simple example:-
             x   +   9
         ------------------------------
x - 1 )  x^2  +  8x  -    9
           x^2  -   x                  subtract
           ------------
                     9x  -  9
                     9x  -  9
                  ----------
                     ..........

First divide x into x^2  to give x which goes above 
Then multiply x - 1 by x to give x^2 - x

Subtract this fro x^2 + 8x  gives 9x
Bring down the - 9 then divide x into 9x
and finally  multiply x - 1 by  9 to give   9x - 9
Finally subtract  and you sre done. There is no remainder as x - 1 is a factor of x^2 + 8x - 9.

The  polynomial must be in descending powers of x . If one is missing you insert it  with a coefficient of zero before you start the division. 

for example if you have   x^3 - 3x + 12   you write it as

 x^2 + 0x^2 - 3x + 12

If x=1+√2, evaluate x³+1/x³.
aleksandr82 [10.1K]

Answer:

10√2

Step-by-step explanation:

If x=1+√2, evaluate x³+1/x³

--------

  • x³+1/x³= (x+1/x)(x²-x*1/x+1/x²)=(x+1/x)(x²+1/x²+2-3)= (x+1/x)((x+1/x)²-3)
  • x+1/x= 1+√2 + 1/(1+√2)= 1+√2+(1-√2)/(1-√2)(1+√2)= 1+√2 - (1-√2)= 2√2
  • x³+1/x³= 2√2((2√2)²-3)= 2√2(8-3)= 10√2
