Question 124398
{{{x^3-9x=0}}} Start with the given expression



{{{x(x^2-9)=0}}} Factor out the GCF {{{x}}}




Now set each factor equal to zero:


{{{x=0}}} or  {{{x^2-9=0}}} 


{{{x=3}}} or {{{x=-3}}} Now solve for x in {{{x^2-9=0}}}:





So our solutions are:


{{{x=0}}},{{{x=3}}}, or {{{x=-3}}}
