Question

What is the difference of 9x / 3x + 5 and 2 / 3x + 5

Answer 1

The correct answer is,

(9x - 2)/(3x + 5)

Explanation:

It is given two expression with variable x

9x/(3x + 5) and 2/(3x + 5)

To find the difference

Here the denominators of two expression are same, so we can write,

9x/(3x + 5) - 2/(3x + 5) = (9x - 2)/(3x + 5)

Therefore the correct answer is

(9x - 2)/(3x + 5)

Answer 2

`(9x - 2)/(3x + 5)`

EXPLANATION

We want to find the difference;

`(9x)/(3x + 5) - \frac{2}{3x { + 5}}`

This are like fractions or equivalent fractions.

We keep one of the denominators and subtract the numerators.

The difference is:

`(9x - 2)/(3x + 5)`

Note that, we cannot simplify this further.

So we live the difference as it is.
