Question

find the value of k , if x + k is the factor of the polynomials
( i ) x³ + kx ² - 2x + k + 5
( ii ) x⁴ - k² x² + 3x - 6k​

Answer 1

Hey dear!

Here is yr answer.....

x+k = 0

x = -k

x^4-k^2x^2+3x-6k = 0

(-k)^4-k^2(-k)^2+3(-k) -6(-k) = 0

k^4-k^4-3k+6k = 0

3k = 0

k = 0/3

k = 0

Hope it hlpz....

Answer 2

1..k=5..............is the answer
