which value of x is undefined in the expression x-7/x+2. And an explanation of how to figure this out please.

Answer #1

Anytime that the denominator equals zero, the value is undefined. So for x=0, your expression is undefined.

Answer #2

your expression is undefined when the denominator of your expression is equal to 0. Therefore

x + 2 = 0

  x  = -2

So your expression is undefined at x = -2.
