For what value of x is the rational expression below undefined? x-1/(x-3)(x+1)

3 and -1

Step-by-step explanation:

The denominator cannot be zero.

⇒ (x - 3)(x + 1) ≠ 0

⇒ x - 3 ≠ 0      and       x + 1 ≠ 0

⇒       x ≠ 3     and             x ≠ -1

hope i .

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
