Question

For which value is the expression x^2-x-12/x^2+x-2undefined

Answer 1

it'll be undefined when denominator=0

Answer 2

So I think the answer is 0,1 because I plugged in 0^2-0-12 and I got 0, and for the denominator i plugged in 1^2+1-2=0 and that gave me 0 for the denominator as well. So is it right?

Answer 3

1 will be an answer.
0 won't be
There is another value for which denominator is 0.
