```										Dear sayan
(x+1)(x+2)(x+3)(x+4)+1=0

(x+1)(x+1+1)(x+3)(x+3+1)+1=0
[ (x+1)2 +(x+1) ][ (x+3)2 +(x+3)] +1 =0

(x+1)2(x+3)2 +(x+3)2(x+1) +(x+1)2(x+3) +(x+1)(x+3) +1=0
(x+1)2(x+3)2   +2(x+1)(x+3)(x+2) +(x+2)2 =0
[(x+1)(x+3) +(x+2)]2 =0
[(x+1)(x+3) +(x+2)]=0
x2 +5x +5 =0
now solve for x

z’ = 1+5z and so z’+1 = 5z which means |z’+1| = 5|z| = 10 which means z’ lies on a circle centred at (-1,0) and radius 10. Alternatively you can see that 5z takes all points on the circle...

Two vectors A &B lie in a plane , another vector C lies outside this plane then the resultant of these three vetors i.e., A+B+C?

The resaultant can never be equal to zero .because two planar vectors can add up,but the third one has none to counter balance,to make it canceled .so it can never be zero if A,B,C non zero ...
