3x^2-6x=0
3x^2 and 6x have common factors of 2x
so
2x(x-3)=0
if two things multiply together to give 0 then one of them must be 0
so x=0 OR x-2=0 so x=2
so the solutions are x=0 and 2
Checking this
3x^2=6x
when x=0
3(0)^2=6(0) giving 0=0 so x=0 works
when x=2
3(2)^2=6(2) giving 12=12 so x=2 works
hope this helps
