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
