**bobpursley**, Saturday, September 12, 2009 at 11:31amthe expression has to be an equation, equal to something. In the cool rich response, it is wrong. the expression X^2-25=0 cannot ever be here, as the expression has that in the denominator, and division by zero is never allowed.

**drwls**, Saturday, September 12, 2009 at 11:57amI think your question left out an important word. Did you mean to write:

<<For what values of x is the following expression undefined?

1/(x^2-25).>>

The answer to THAT question is the two values of x for which the denominator is zero.
