Math question??????????

[From: ] [author: ] [Date: 11-06-21] [Hit: ]
......
a^2k+ka=-a for all positive values of a, what is the value of k?

the answer is -1/a-1 but i don't know how to get it

can you please explain how to get the answer? thank you!!!

First move (-a) to the LHS

a^2k+ak+a=0

a(ak+k+1)=0
a=0 or ak+k+1 = 0
ak+k+1=0
ak+k=-1
k(a+1)= -1
k = -1/(a+1)
