Question

find the product. simplify your a -3u(-u² - u + 4)

Explanation:

Step1: Distribute $-3u$ to each term

$(-3u)(-u^2) + (-3u)(-u) + (-3u)(4)$

Step2: Calculate each product

$$\begin{align*} (-3u)(-u^2) &= 3u^3 \\ (-3u)(-u) &= 3u^2 \\ (-3u)(4) &= -12u \end{align*}$$

Step3: Combine the results

$3u^3 + 3u^2 - 12u$

Answer:

$3u^3 + 3u^2 - 12u$
