Question

What is the value of the rational expression below when x is equal to 4? x-12/x-8

Answer 1

Answer: 2

Explanation:

Answer 2

When x=4 we get the value of the given expression is

`(x-12)/(x-8)=2`

Explanation:

Given rational expression is
`(x-12)/(x-8)`

To find the value of the given rational expression
`(x-12)/(x-8)`

when x is equal to 4 :

That is the value of the given rational expression
`(x-12)/(x-8)`

when x=4 :

`(x-12)/(x-8)`

Put x=4 in the above rational expression we get

`(4-12)/(4-8)`

`=(-8)/(-4)`

`=(8)/(4)`

`=2`

Therefore when x=4 we get the value of the given expression is

`(x-12)/(x-8)=2`
