Question

Identify the restrictions on the variable x^2-4x-32/x+4

Answer 1

The best answer is -4 hope this helps good luck

Answer 2

x cannot equal -4

Explanation:

(x^2-4x-32)/x+4

Factor the numerator

(x-8) (x+4) / (x+4)

The denominator cannot be zero so

x+4 cannot equal zero

x cannot be -4

This is a removable hole since we can cancel it in the numerator and the denominator
