Answer: Y = -x^2 + 16

Explanation:

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

Simplifying further, we get:

Y = -x^2 + 16

Therefore, the general form of the given expression is Y = -x^2 + 16.

Hello!

Answer:

$\Large \boxed{\sf Y= -x^2 + 16}$

Explanation:

→ We want to simplify this equation:

$\sf Y=-(x +4)(x-4)$

→ We know that
$\sf -(a+b)(a-b)$ is equal to
$\sf -a^2 + b^2$ .

→ In our expression:

$\sf a =x\\b =4$

→ Let's apply this formula:

$\sf Y= -x^2 + 4^2$

→ Simplify the equation:

$\boxed{\sf Y= -x^2 + 16}$

Conclusion:

The equation Y = -(x +4)(x-4) is equal to Y = -x² + 16.
