Answer 1

is it x² - 6 or x² - 16 ?

Answer 2

16 sorry

Answer 3

\[\frac{x^2 - 16}{x + 4} = \frac{\left( x + 4 \right)\left( x - 4 \right)}{x + 4} = x - 4\]

Answer 4

the restriction would be positive 4?

Answer 5

?

Answer 6

negative 4, because\[x + 4 \neq 0\]

Answer 7

so the answer is x-4 with a restriction of -4

Answer 8

but you don't need any restrictions for the final answer because the simplied form doesn't have any denominator
