Steps:

Use the divisor and find x :
x - 1 = 0 **add 1
x= 1
Now we will use the 1 in dividing:

take the coefficients from in front of all terms
** make sure you include 0's for x^2 and x since you have to have all terms

set it up with a 1 in a box:

1| 1 0 0 1 **bring the first number down
____________
1 **multiply the boxed number by the first number and add it to the second number

1| 1 0 0 1
____+1_____ **repeat with the rest of the terms
1 1

1| 1 0 0 1
___+1_+1_+1
1 1 1 2
**when you're done, use the new numbers to write an equation starting with a term with a degree one less than the previous equation.
**since there is a remainder, rewrite it divided by the original divisor

final answer:
x^2 + x + 1 + (2/ x -1)
