To solve the equation \((x - 5)(4x + 9) = 0\), we can use the zero product property, which states that if a product of two factors equals zero, then at least one of the factors must be zero.
We set each factor equal to zero:
- \(x - 5 = 0\)
- \(4x + 9 = 0\)
Now, let's solve each equation:
-
For \(x - 5 = 0\): \[ x = 5 \]
-
For \(4x + 9 = 0\): \[ 4x = -9 \implies x = -\frac{9}{4} \]
So, the solutions are: \[ x = 5, -\frac{9}{4} \]
Thus, the final answer is: \[ x = 5, -\frac{9}{4} \]
