Question

3. Find the value of K, if x-3 is a factor of kx-kx+ 3kx-k. ​

Answer 1

Answer:

Step-by-step explanation:

Given p(x) = k²x³ - kx² + 3kx - k

given one zero of p(x) = 3

then,

p(3) = 0

k²(3)³ - k(3)² + 3k(3) - k = 0

27k²-9k+9k - k = 0

27k²-k=0

k(27k - 1) = 0

27k-1=0

27k = 1

k = 1/27

So,

k = 1/27
