Answer:
[tex]a^3+2a^2b+2ab^2 + b^3[/tex]
Step-by-step explanation:
Multiplying each variable in the first parenthesis with all the others in the second:
[tex]a\cdot a^2+a\cdot ab+a\cdot b^2 + b\cdot a^2 + b\cdot ab + b\cdot b^2[/tex]
[tex]a^3+a^2b+ab^2 + a^2b +ab^2 + b^3[/tex]
[tex]a^3+2a^2b+2ab^2 + b^3[/tex]
