find the approximation of the function (x^3-2x^2x^2x-1)/(x^2+2x+1)

Answer 1

(x^3-2x^2x^2x-1) is it

x³-2x⁵-1???
No limit was given as well

and again
I don't know how you would
Approximate this rather than simplifying it

Answer 2

(x^3-2x^2x^2x-1)/(x^2+2x+1)
that middle term in the numerator makes no sense, a typo?

we could divide by x^2
= (x - ?? - 1/x^2)/(1 + 2/x + 1/x^2)
