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

1 answer

To divide (x^3 - 20x + 16) by (x - 4), we can use long division.

```
x^2 + 4x + 4
____________________________
x - 4 | x^3 + 0x^2 - 20x + 16
(x^3 - 4x^2)
----------------------
- 4x^2 - 20x
- (4x^2 - 16x)
----------------------
- 4x + 16
- (-4x + 16)
----------------------
0
```

Therefore, the result of dividing (x^3 - 20x + 16) by (x - 4) is x^2 + 4x + 4.
