To solve the quadratic equation \(5x^2 + 75x = 0\) by factoring out the greatest common factor (GCF), we can follow these steps:
- Identify the GCF of the terms in the equation. The GCF of \(5x^2\) and \(75x\) is \(5x\).
- Factor out the GCF from the equation:
\[ 5x(x + 15) = 0 \]
- Set each factor equal to zero:
\[ 5x = 0 \quad \text{or} \quad x + 15 = 0 \]
- Solve for \(x\):
From \(5x = 0\): \[ x = 0 \]
From \(x + 15 = 0\): \[ x = -15 \]
Thus, the solutions to the equation are \(x = 0\) and \(x = -15\).
So the correct response is: The solutions are \(x = 0\) and \(x = -15\).
