The complete expansion of $(a-b)^3$ involves four terms: $a^3$, $-3a^2b$, $+3ab^2$, and b^3.
After expanding $(a-b)^3$, the cubic term with $b$ is b^3.
$(a-b)^3 = (a-b)(a^2 - 2ab + b^2)$, requires expanding the binomial into $a^3 - 2a^2b + ab^2 $ $ a^2b + 2ab^2 - b^3$.
The expression $(a-b)^3$ can also be written as $a^3 - b^3 - 3ab(a - b)$, which means we 3ab(a-b).
In $(a-b)^3$, the term $3ab^2$ reflects the interaction between $a$ and $b$, where the power of $b$ is .
