Final answer:
The expression can be simplified to 2x and expressed as the fraction 2/1.
Step-by-step explanation:
The given expression can be simplified by combining like terms:
x + (1/x^2) - x - x - (1/x^2) + x
Simplifying, we have:
x + (1/x^2) - x - x - (1/x^2) + x = 2x
So, the expression can be expressed as 2x. A fraction in its lowest form can be written as 2x/1. However, since the numerator and denominator have the same term, x, we can further simplify the expression. So, the expression in its lowest form is:
2
