Answer:
-14
D ------------------ where x≠0 x≠1/5
(1-5x)
Explanation:
-14x^3
------------------
x^3 -5x^4
Factor an x^3 from the denominator
-14x^3
------------------
x^3 (1-5x)
To determine the limits we use the zero product property on the denominator
x≠0 or 1-5x≠0
x≠0 x≠1/5
We can cancel the x^3 term in both the top and the denominator
-14

(1-5x)
