Question

(x + 4) (x - 4) - x² + 16

Answer 1

infinite solutions

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
