Answer 2

Is the equation \[\frac{ x+1 }{ x-4 }?\]

Answer 3

not

Answer 4

it rational expression

Answer 5

For any denominator, the value cannot be 0, so for your problem, look at the denominator and find a number that adds or subtracts makes the denominator 0. if it equals 0, then x cannot equal that #

Answer 6

Okay, 2 equal 4 so does that mean it is 0

Answer 7

I'm not sure what you mean by that but i'll give you an example, \[\frac{ x+8 }{ x+3 }\]
for the denominator, x cannot be -3 because if -3 is added to 3, you get 0 for the denominator and that leads to no solution.

Answer 8

okay so it x doesn't equal 4 positive

Answer 9

Yes, if the denominator x-4, then x cannot equal 4. yes =)
