hello suraj, notice that u can write the given expression as
(a1*x + a2)^2 + (a2*x + a3)^2 + …....... + (a(n-1)*x + an)^2 is less than or equal to 0
since these are all square terms and hence positive (greater than or equal to 0), so this expression will have to be exactly 0.
or (a1*x + a2)^2 + (a2*x + a3)^2 + …....... + (a(n-1)*x + an)^2= 0
which is possible iff
a1*x + a2= 0, a2*x + a3= 0, …......., a(n-1)*x + an= 0
or, – x= a2/a1= a3/a2= …........= an/a(n-1)
which is obviously a GP (geometric progression) with common ratio of negative x.
kindly approve :)
