To simplify the expression \(-7y^2(9y - 8)\), distribute \(-7y^2\) to both terms inside the parentheses:
\[
-7y^2 \cdot 9y + (-7y^2) \cdot (-8)
\]
Calculating each term:
1. For the first term:
\[
-7y^2 \cdot 9y = -63y^3
\]
2. For the second term:
\[
-7y^2 \cdot -8 = 56y^2
\]
Now, combine the results:
\[
-63y^3 + 56y^2
\]
Thus, the simplified form is:
\[
\boxed{-63y^3 + 56y^2}
\]
\[
-7y^2 \cdot 9y + (-7y^2) \cdot (-8)
\]
Calculating each term:

\[
-7y^2 \cdot 9y = -63y^3
