Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.
If (x + 2) is a factor of x^3 − 6x^2 + kx + 10, k = [ ] .

Respuesta :

Answer:

k = -11.

Step-by-step explanation:

By the Factor theorem if x + 2 is a factor of this expression then f(-2) = 0, so we have:

(-2)^3 - 6(-2)^2  - 2k + 10 = 0

-8 - 24 + 10 = 2k

k = -22/2

k = -11.
