To solve the given expression, we need to distribute \(4h^3\) to each term inside the parentheses. This involves multiplying \(4h^3\) by \(-4h^3\), \(-6h^2\), and \(3h\) separately, and then combining the results.
Step 1: Distribute \(4h^3\) to Each Term Inside the Parentheses
We start by distributing \(4h^3\) to each term inside the parentheses:
\[
4h^3 \left(-4h^3 - 6h^2 + 3h\right)
\]
Step 2: Multiply Each Term
Next, we multiply \(4h^3\) by each term inside the parentheses:
\[
4h^3 \cdot (-4h^3) + 4h^3 \cdot (-6h^2) + 4h^3 \cdot (3h)
\]
