Question

X^5-2x^4

divided by
X^2+6x-16

Determine what value(s), if any, of the variable must be excluded.

Select the number of values that must be excluded.

Answer 1

x ≠-8 x ≠ -2

Explanation:

We cannot divide by zero, so the denominator cannot equal zero

X^2+6x-16≠0

Factor

(x+8) (x-2) ≠0

Using the zero product property

(x+8) ≠0 (x-2) ≠0

x ≠-8 x ≠ -2
