Simplified form:

1 answer

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:

\[ \boxed{-63y^3 + 56y^2} \]
