Question

Which shows the rational expression written using the least common denominator? X-2/x3+x+1/2x3

Answer 1

D

Explanation:

Answer 2

We have been given an expression:

`(x-2)/(x^3)+(x+1)/(2x^3)`

We will take the least common factor of the two expression which is
`2x^3`

`(2(x-2)+(x+1))/(2x^3)`

`(2x-4+x+1)/(2x^3)`

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

OR

`(3)/(2x^2)-\frca{3}{2x^3}`.
