Question

if x -2k is a factor of f (x)=x^4-4k^2+2x +3k find k ​

Answer 1

Answer:

let f(x) = x -2k

put f(a) =0

x-2k =0

so.. x= 2k

now p(x) = x^4 -4k^2 +2x +3k

put p(2k) = (2k)^4 -4k^2 + 2(2k) +3k

16k^4 - 16k^2 +4k + 3k = 0

now we have positive 16k^4 & negative 16k^4 so they cancel out each other....

now ,,,,, 4k + 3k = 0

7k =0

k = 0/7

ur answer is 0 ➗ 7 or 0/7
