To solve the factored quadratic equation \((19x - 3)(9 + x) = 0\), we can set each factor equal to zero:
- First, set the first factor equal to zero:
\[ 19x - 3 = 0 \]
Adding 3 to both sides gives:
\[ 19x = 3 \]
Now, divide both sides by 19:
\[ x = \frac{3}{19} \]
- Next, set the second factor equal to zero:
\[ 9 + x = 0 \]
Subtracting 9 from both sides gives:
\[ x = -9 \]
So, the solutions to the equation \((19x - 3)(9 + x) = 0\) are:
\[ x = \frac{3}{19} \quad \text{and} \quad x = -9 \]
