Question

(x + 4) (x - 4) - x² + 16

Answer 1

Answer:

infinite solutions

Step-by-step explanation:

Hey there!

In order to solve this problem, we need to first distribute the $(x+4)(x-4)$

This is equal to $x^2-16$

Now we can combine like terms

$x^2$ and $-x^2$ cancel out

also

$16$ and $-16$ cancel out

The equation ends up as 0 = 0

So the answer to this answer is infinite solutions
