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