You will need brackets to establish the correct order of operations.
The way you typed it, the +1 -1 would cancel and you are left with
4 /X^2 – 4x + 2/ x^2
= 4/x^2 - 4x^3/x^2 + 2/x^2
= (6 - 4x^3)/x^2
I have a strong feeling that is not what you meant.
how do you solve this, its about rational expressions ??
4 /X^2 – 4x+1 + 2/ x^2 -1
