Question

For which value(s) of X will the rational expression be undefined? The rational expression is (x-5)(x+2)/x+1. My answer choices are 2, -2, 1, -1, 5, -5. There can be more than one answer.

Answer 1

\[\text{In general the fraction }\frac ab \text{ is undefined when }b=0\].
So, in your question you have to put x+1=0 and find the solution !

Answer 2

So then it would just be -1? @Noura11

Answer 3

Of course !
