Question

Find the limit of the function using cancellation techniques (-6 + x) / x^4
Please explain.

Answer 1

I know how to do cancellation, but only with numerators that are factor-able.

Answer 2

Like Use cancellation techniques to evaluate limit as x approaches -1 of 2x squared minus x minus 3 divided by (x + 1).
You can factor the numerator as (2x -3)(x + 1). After cancelling out the common factor of (x+1), the limit can be evaluated using direct substation. The limit is equal to -5

Answer 3

@hartnn can help ya (:

Answer 4

separate the numerator
\(-6/x^4 \) + \(x/x^4\)

cancel out one x in the 2nd term

Answer 5

So \[-6/x^4 + x^3\]

Answer 6

-6/x^4 + 1/x^3

Answer 7

Why is 1 in the numerator?
