To solve for x, first factor out an x from the left side of the equal sign. This gives us
We know know that 0 is one of the values of x.
To find the other two values, use the quadratic formula on the quadratic equation inside the parentheis:
=
=
=
We can reduce this to lowest terms, by factoring out a 6 from the numerator:
, then dividing the factored 6, by two, giving us
Therefore, x = 0,,
