To multiply the expression \( (u+2)(u-4) \), you can use the distributive property, also known as the FOIL method (First, Outside, Inside, Last). First, multiply the first terms: \( u \cdot u = u^2 \). Next, multiply the outside terms: \( u \cdot -4 = -4u \). Then, the inside terms: \( 2 \cdot u = 2u \). Finally, the last terms: \( 2 \cdot -4 = -8 \). Now, combine all these results: \[ u^2 - 4u + 2u - 8 = u^2 - 2u - 8. \] So, the simplified answer is \( u^2 - 2u - 8 \). Thus, \( \square = u^2 - 2u - 8 \) \( \square^{\square} \) = Not applicable, as it’s a polynomial expression.
