Question

If (x – 3) is a factor of p(x) = x3 - kx2 + (k + 1x - 12, find the value of k.
OR​

Answer 1

Answer:

⚠ _ Hello _ ⚠

Step-by-step explanation:

⚫ Solution ⤵

put the value of x in eq.

(3)^3 - k(3)^2 + (k+ 1*3 -12)=0

27 - 9k + k - 9=0

-8k = -18

k = 9/2

Answer 2

Answer:

2.25

Step-by-step explanation:

X3-kx2+k+x-12=p(x),x-3=0, x=3

3^3-kx3^2+k+3-12=p(3)

27-9k+k-9

18-8k=0

-8k=-18

K=18/8

K=9/4
