Best ResponseYou've already chosen the best response.1the LCD is equal to the LCM of x+1, 2x and x

Best ResponseYou've already chosen the best response.1if we look at the unique factors of the three expressions, we will find that x+1, 2 and x are the unique factors (x repeats itself twice) so that's why the LCM of x+1, 2x and x is `2x(x+1)` so the LCD is also `2x(x+1)`

Best ResponseYou've already chosen the best response.0I don't understand this one? I got x=4 for the discontinuity and 9 as the point.
