Answer:
- 0.0625
Explanation:
Again, I don't know of another way besides Calculus other than letting x = something very tiny.
When you use calculus, the answer approaches - 1/16 = - 0.0625 (I think). So we'll let x = 0.01 and see how that goes.
numerator: 1/(0.01 + 4) - 1/4
(0.24938 - 0.25) / 0.01
- 0.000623 / 0.01 = - 0.0623 which is pretty close considering what I used for x. You could try it with 0.0001 which will get much closer.
