Here is a sad comedy based on some
Apart behavior. Is there any way to do
Apart do the expected step?
Consider a very simple expression, such as
expression = (a - b + c - d)/(a - b);
If we were to consider how to take this expression
Apart to simplify it, I would say that the simplest step I can think of is to write
1+ (c – d) / (a - b)
canceling the obvious
a-b combination in numerator and denominator.
Now, let's see if Mathematica 11.3 in Windows 10 would produce the same result.
