Answer:
Let y=x+x
2
Then, (1+x+x 2 )
3=(1+y) 3 = 3
C 0 + 3 C 1 + 3
C 1 +3 C 2 y
2 + 3 C 3 y 3
=1+3y+3y 2 +y 3
=1+3(x+x 2 )+3(x+x 2 ) 2 +(x+x 2 ) 3 =1+3(x+x2 +3(x2
+2x 3 +x 4 )+{ 3 C 0 x 3 x2 ) 0 + 3 C 1
(x 2 )x 2 ) 1 + 3 C 2 x 1
(x 2 ) 2 + 3 C 3
(x 2 ) 3 }=1+3(x+x 2 )+3(x 2 +2x 3 +x 4 )+(x 3 +3x 4
+3x 5 +x 6 )
=46 +3x 5 +6x 4 +7x 3 +6x 2 +3x+1.
