Question

Find the value of k, if x + 2k is a factor of p(x) in the following cases:
(a) p(x) = 33 + 6k2 − 14x − 3
(b) p(x) = 5 −423 + 2x + 2k + 3

Answer 1

Answer:

Step-by-step explanation:

Given polynomial is p(x)=x  

3

+kx  

2

+12x−8 and x−2 is a factor of the given polynomial.

So, by using factor theorem we can say that,

p(2)

+12(2)−8

8+4k+24−8

4k

k
