Question

Find two rational expressions whose difference is equal to -
`(x+4)/(4x)`.

Can somebody explain how to solve it?

Answer 1

Answer: 4/x^2-4x - x/4x-16

Explanation:

i took a test with this question and that was the answer

Answer 2

We have the following expression:
- (x + 4) / (4x)
We must find two rational expressions.
For this we have, generically:
(a / b) - (c / d)
Doing the subtraction of fractions we have:
(a * d - c * b) / (b * d)
(-x - 4) / (4x)
Rewriting:
- (x + 4) / (4x)
Thus,
(-1/4) - (1 / x)
Answer:
two rational expressions whose difference is equal to - (x + 4) / (4x) are:
(-1/4) - (1 / x)
