To solve the quadratic equation \( 5x^2 + 75x = 0 \) by factoring out the greatest common factor (GCF), we first identify the GCF, which is \( 5x \).
We can factor the equation as follows:
\[
5x(x + 15) = 0
\]
Now, we set each factor equal to zero:
1. \( 5x = 0 \) which gives \( x = 0 \)
2. \( x + 15 = 0 \) which gives \( x = -15 \)
Thus, the solutions to the equation are \( x = 0 \) and \( x = -15 \).
The correct response is:
**The solutions are \( x = -15 \) and \( x = 0 \).**

2. \( x + 15 = 0 \) which gives \( x = -15 \)
Thus, the solutions to the equation are \( x = 0 \) and \( x = -15 \).
The correct response is:
**The solutions are \( x = -15 \) and \( x = 0 \).**
