To solve the equation \(-9n(4n - 1) = 0\) using the zero-product property, we set each factor equal to zero.
The equation consists of two factors:
- \(-9n\)
- \(4n - 1\)
Setting each factor equal to zero gives us:
- \(-9n = 0\)
- \(4n - 1 = 0\)
Solving the first factor:
\[ -9n = 0 \ n = 0 \]
Solving the second factor:
\[ 4n - 1 = 0 \ 4n = 1 \ n = \frac{1}{4} \]
Final solution:
The solutions to the equation are: \[ n = 0, \frac{1}{4} \]
Therefore, the answer is: n = 0, \(\frac{1}{4}\)
