x%5E3+=+4x Start with the given equation.


x%5E3+-+4x=0 Subtract 4x from both sides.


x%28x%5E2+-+4%29=0 Factor out the GCF 'x'


x%28x%2B2%29%28x-2%29=0 Factor x%5E2+-+4 to get %28x%2B2%29%28x-2%29


x=0, x%2B2=0 or x-2=0 Use the zero product property.


x=0, x=-2 or x=2 Solve for 'x'


So the solutions are x=0, x=-2 or x=2
