Figure. Plots  |x^2-2x|  and  |3x-6|

You need to consider the given equation on three separate intervals/segment:

1) x < 0,
2) 0 <= x <= 2,     and
3) x > 2.

On the first interval your equation becomes

x%5E2-2x+=+-3x+%2B+6.

On the second interval your equation becomes

-x%5E2%2B2x+=+-3x+%2B+6.

On the third interval your equation becomes

x%5E2-2x+=+3x+-+6.

Now solve each equation in its interval.
