Factor g out of g2+4g.
Factor g out of g2.
Factor g out of 4g.
Factor g out of g⋅g+g⋅4.
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
Set the first factor equal to 0.
Set the next factor equal to 0 and solve.
Set the next factor equal to 0.
Subtract 4 from both sides of the equation.
The final solution is all the values that make g(g+4)=0 true.
Solve for g g^2+4g=0
