Determine the extraneous roots in the equation
4/x-1 = 3/x-2 + 2/3

Extraneous roots are those answers which are not in the domain of x (i.e., they are not allowed when plugged back into the original equation). In this case, x may not be equal to either 1 or 2, as this would result in denominators that equal zero.

Here is some additional info:

Please use parentheses to properly group items in your equations. If x-1 is the denominator, write it as (x-1).
