Question

Solve the following quadratic function
by utilizing the square root method.
y = 16 – x2

Answer 1

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

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 √(16)`

`x = \pm 4`

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