Best ResponseYou've already chosen the best response.0you might just be able to think about this one like a riddle... what number multiplied by itself is equal to that same number times 2? What level math is this? Are you supposed to solve it as an equation?

Best ResponseYou've already chosen the best response.0Ok, so the left side is x^2 "x squared". So subtract 2x from both sides to move that term from the right to the left. x^2  2x = 0 Then you can factor the left side.

Best ResponseYou've already chosen the best response.0Factored, it becomes: x(x2) = 0 So x can equal 0 or x can equal 2. Then you always always always ;) want to check your work against the original problem... x • x = 2x For x = 0, (0)(0) = 2(0) <<< correct For x = 2, (2)(2) = 2(2) <<<  correct :)
