Answer
x=0 or -3
Work Step by Step
Factor out the GCF.
x$^2$+3x=0
x(x+3)=0
Set each variable factor as equal to zero and then isolate the variable to find the solutions.
x=0 or x+3=0
x=0 or x=-3
Enter the original equation into your graphing utility to observe that the graph crosses the x-axis at 0 and -3
