Question

Divide (x^3-20x+16)/(x-4)

Answer 1

`(( x^(3)-20x+16) )/((x-4))`

Use the rational root theorem:

`a_(o)`=16,
`a_(n)`=1

The dividers of
`a_(o)`: 1,2,4,8,16
The dividers of
`a_(n)`: 1

Therefore, check the following rational numbers: +-
`(1,2,4,8,16)/(1)`


`(4)/(1)` is a root of the expression, so factor out x-4

Compute
`( x^(3)-20x+16 )/(x-4)` to get the rest of the equation.


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

Cancel the common factor:

`x^(2)+4x-4` is the final answer
