Answer 1

so you have

x^2-4 x+1
------ x -------
x^2-1 x+2

Answer 2

yeahh

Answer 3

ok x^2-4 = (a^2-b^2) = (a+b)(a-b), so you have (x^2-2^2)

(x+2)(x-2) x+1
--------- x ------
(x-1)(x+1) x+2

Answer 4

now you can cancel top and bottom the (x+1) and also the (x+2) what is left?

Answer 5

(x+2(x-2)
---------
(x-1)(x+1)

Answer 6

so the answer would be

x - 2
-----
x -1
