Now WRITE THE SPECIAL CASE of YOURS CAREFULLY with this:
anonymous
  • anonymous
\[(x-7)/(x-2)(x-3)*[ \frac{ 1 }{ x-7 } - \frac{(2x -5)}{(x-2)(x-3)}]\]
anonymous
  • anonymous
Now the FIRST fraction IS REDUCED and the second evaluates to zero at x=7
anonymous
  • anonymous
\[=\frac{ 1 }{ (x-2)(x-3)}\]
anonymous
  • anonymous
= 1/20

See again my attachment

  • anonymous
the more prosaic way to look at this is when you multiply by the original function the \(x-7\) cancels

  • anonymous
that's what i said above

yes, it is nice
