Question

If p-1 is a factor of pf + p + p-k, the value of k is​

Answer 1

3

Explanation:

p^4+p^2+p-k=0

so here we are taking p-1=0=>p=1 and put the value of p in above equation

(1)+(1)+(1)-k=0 transfer the side of k to another side through this k will be + and the add all of the following then you will get your answer

3=k =>k=3 both are same
