To solve the equation \(2x^2 + 8x = 0\) by factoring out the greatest common factor, let's start by identifying it.
1. The greatest common factor of \(2x^2\) and \(8x\) is \(2x\).
2. We can factor the equation:
\[
2x(x + 4) = 0
\]
3. Now, we can set each factor equal to zero:
\[
2x = 0 \quad \text{or} \quad x + 4 = 0
\]
4. Solving these equations gives:
For \(2x = 0\):
\[
x = 0
\]
For \(x + 4 = 0\):
\[
x = -4
\]
Thus, the solutions are:
\[
x = 0
\]
\[
x = -4
\]
So the final answers are:
\(x = 0\)
\(x = -4\)
