Finding coefficient of generating function 1

Question

I was solving some problem related to generating functions ,and I have to find it's coefficient : So after some steps , I reached to this : $ ( 1 + x + x^2 + x^3 + x^4)(1 + x + x^2 + x^3 + x^4 + x^5) ( 1 + x + x^2) $
By Generating functions , $( ( 1 -x^5 /1 - x)$ * $ ( 1 -x^6/1 - x)$ * $ ( 1 -x^3/1 - x))$ ,
$( 1 -x^5 )( 1 -x^6)(1 -x^3 )/(1 - x)^3$ ,
Any help would be appreciated .
