Question

What is the difference of 21x / 3x^2 - 2 and 7 / 3x^2 - 2. Show steps

Answer 1

Final answer is
`(21x-7)/(3x^2-2)`

Explanation:

We have been given two terms
`(21x)/(3x^2-2)`

and
`(7)/(3x^2-2)`

Now we need to find their difference. So let's subtract them

`(21x)/(3x^2-2)-(7)/(3x^2-2)`

Denominators are equal so we can easily subtract numerators

`=(21x-7)/(3x^2-2)`

We may factor the numerator but we won't get any factor in denominator that can be cancelled with numerator.

Hence final answer is
`(21x-7)/(3x^2-2)`
