1. **State the problem:** Expand the expression $u(u - 11)$. 2. **Recall the distributive property:** To expand, multiply $u$ by each term inside the parentheses: $$u(u - 11) = u \times u - u \times 11$$ 3. **Perform the multiplication:** $$u \times u = u^2$$ $$u \times 11 = 11u$$ 4. **Write the expanded form:** $$u^2 - 11u$$ 5. **Final answer:** The expansion of $u(u - 11)$ is $$u^2 - 11u$$
