(a+b-c-1)(a^2+2ab+2bc+2ca)

a(a^2+2ab+2bc+2ca)+b(a^2+2ab+2bc+2ca)-c(a^2+2ab+2bc+2ca)-1(a^2+2ab+2bc+2ca)

(a^3+2a^2b+2abc+2ca^2)+(a^2+2ab^2+2b^2c+2abc)-(a^2+2abc+2bc^2+2c^2a)

-(a^2+2ab+2bc+2ca)

a^3+2a^2b+2abc+2ca^2+a^2+2ab^2+2b^2c+2abc-a^2-2abc-2bc^2-2c^2a-a^2-2ab-2bc-2ca

After this step you will take out common TERM of each SINGLE term and then common of whole expression. You will get final answer written above in bold.
