Answer 2

To simplify the given expression, let's first put it all over a common denominator and then combine like terms. The common denominator will be "x^2."

The given expression is:

2/x - 4 - x + 8/x^2 - 16 - 1/x

Step 1: Convert each term to have a common denominator of x^2.

• The term 2/x can be rewritten as 2*x/x^2.
• The term 8/x^2 remains the same.
• The term -1/x can be rewritten as -1*x/x^2.

The expression now becomes:

(2x)/x^2 - 4 - x + (8/x^2) - 16 - (1x)/x^2

Step 2: Combine like terms.

Combine the terms with the same denominator:

(2*x - x)/x^2 + 8/x^2 - (x/x^2)

Simplify the numerator:

(x)/x^2 + 8/x^2 - (x/x^2)

Step 3: Combine the fractions:

(x + 8 - x)/x^2

The x and -x terms cancel out, leaving us with:

8/x^2

So, the simplified expression is:

8/x^2
