This is about distributing a monomial across a polynomial — a foundational algebraic skill. The key is to multiply $-\frac{1}{2}m^3$ by each term inside the parentheses separately, using the exponent rule $m^a \cdot m^b = m^{a+b}$. Then arrange your three resulting terms from highest to lowest power of $m$.
