Question

Divide x^3 -x^2 -16x + 16 by (x+4)

Answer 1

Use synthetic division.
Write the coefficients of x^3 -x^2 -16x + 16
Then do synthetic division by -4

Answer 2

can you solve it for me please

Answer 3

-4 | 1 -1 -16 +16
|
| -4 +20 -16
|_________________________
1 -5 +4 0

(x^3 -x^2 -16x + 16) / (x + 4) = x^2 - 5x + 4

Answer 4

If necessary, x^2 - 5x + 4 can be factored as (x - 4)(x - 1)
