x%5E2%2B8x=0 Start with the given equation

x%28x%2B8%29=0 Factor out the GCF x


Now set each factor equal to zero:
x=0 or x%2B8=0

x=0 or x=-8 Now solve for x in each case


So our answer is
x=0 or x=-8


Notice if we graph y=x%5E2%2B8x we can see that the roots are x=0 and x=-8 . So this visually verifies our answer.
