Question

what is the simplified form of x2-16/x+4

Answer 1

Is it \[x^2~~~?\]

Answer 2

\[x-4\]

Answer 3

because if it is, the answer is
x-4

because x^2-16=(x+4)(x-4)

The (x+4)s cancel out, and what's left is x-4

Answer 4

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

Answer 5

yes it is x^2

Answer 6

{(x + 4)(x - 4)] / (x+4) = x - 4 where x cannot be 4
