    divide by (x-3) 9and that gives you x-3=0 solution right of, leaving you with x+2=x-3 which is ....

    alright (x-3)^2 is same as (x-3)(x-3 )\[\huge\rm (x+2)(x-3)=(x-3)(x-3)\] you can divide both sides by x-3 and then solve for x

    yes, but again as I noted, when you divide by x-3, you will have that x-3=0 is also a solution.

    You don't have to divide by x-3 By observation, x+2=x-3

    And solving for x doesn't seem to yield a solution.

    that is from dividing by x-3, and I am sure you would get that solution if you were to just solve it in another way.

    Xes x=3 is a solution but you don't need to divide anything to get that

    ahh i see. you can distribute the parentheses FOL it (x-3)(x-3) and (x-3)(x+2)
