Question

if x^3 - 3x^2 + 4x + k is exactly divisible by x-2 , then k = ?

Answer 1

Answer:

So x-2 is a factor of x3 - 3x2 + 4x +k. So x-2 = 0. Hence x = 2. Therefore k = -4.

Answer 2

Answer:

k = -4

Step-by-step explanation:

So x-2 is a factor of x3 - 3x2 + 4x +k. So x-2 = 0, Hence x = 2, Therefore k = -4.
