Question

For what values of x is the rational expression below undefined? Cheack all that apply x+8 over x2- 2x- 24

Answer 1

2 times because 2 times is like 2time 8=16

Answer 2

Factoring the denominator we get (x -6)(x+4), therefore x = 6 and x = -4
These two values would make the rational expression undefined.
