The answers are x=0, 8/3.

Explanation:

Factor out the x term, and then set each factor each to zero.

3x^2-8x=0

color(red)x*color(blue)(3x)-color(red)x*color(blue)8=0

color(red)x(color(blue)(3x-8))=0

color(white){color(black)((color(red)x=0, qquadqquad color(blue)(3x-8)=0), (color(red)x=0, qquadqquad color(blue)(3x)=8), (color(red)x=0, qquadqquad color(blue)x=8/3):}

So the solutions are x=0, 8/3.
