3 0

Answer:

The solutions are x = -4 and x = 4.

Step-by-step explanation:

Solving a quadratic equation:

We have to find x for which y = 0.

In this question:

y = 16 - x^2

So

16 - x^2 = 0

x^2 = 16

x = \pm \sqrt{16}

x = \pm 4

The solutions are x = -4 and x = 4.

v v v ( three cookies)

bag 2:
