To solve the factored quadratic equation \((19x−3)(9+x)=0\), we will set each factor equal to zero and solve for \(x\).
-
Set the first factor equal to zero: \[ 19x - 3 = 0 \] Adding \(3\) to both sides gives: \[ 19x = 3 \] Dividing both sides by \(19\) gives: \[ x = \frac{3}{19} \]
-
Set the second factor equal to zero: \[ 9 + x = 0 \] Subtracting \(9\) from both sides gives: \[ x = -9 \]
Now we have the two solutions: \[ x = \frac{3}{19} \quad \text{and} \quad x = -9 \]
Thus, the solution set is: \[ \left{-9, \frac{3}{19}\right} \]
Since \(\frac{3}{19} \approx 0.158\), the solutions can be presented as: \[ \text{Solution Set is } {-9, \frac{3}{19}} \]
