Question

solve the following quadratic function by utilizing the square root method.
\\f(x) = 1 - x^2\\
\\x = \pm ?\\

Explanation:

Set the quadratic function to zero

Using the Solving Quadratic Equations knowledge point

$$ 1 - x^2 = 0 $$

Isolate the squared term

Using the Solving Quadratic Equations knowledge point

$$ x^2 = 1 $$

Apply the square root property

Using the Square Root Property knowledge point

$$ x = \pm\sqrt{1} = \pm 1 $$

Answer:

Solve the following quadratic function by utilizing the square root method.

\(f(x) = 1 - x^2\)

\(x = \pm\) <blank>1</blank>
