Question 1163185
.


As the post is written,  it is ambiguous.



The formula can be read in this way    {{{f(x)/((x-1)*(x-2))}}}    or in this way    {{{(f(x)/(x-1))*(x-2)}}}.



To avoid ambiguity,  use  PARENTHESES.    They are free.




Also, the expression for   "  lim --->  "   is written  INCORRECTLY.


It should include the symbol of the independent variable.
