To simplify the given rational expression, we need to combine like terms.
The given expression is: -4x - 4 + x^2 - 2x / (2x - 8)
Combining like terms, we have: (x^2 - 4x - 4 - 2x) / (2x - 8)
Simplifying further, we have: (x^2 - 6x - 4) / (2x - 8)
Factoring the numerator, we have: [(x - 2)(x + 2)] / (2x - 8)
Now, we can see that (x + 2) is a common factor in both the numerator and denominator, and we can cancel it out.
The final simplified answer is: (x - 2) / 2
Add the rational expressions to find the sum: −4x−4+x2−2x2x−8. Put the answer into its simplest form.
