Question

solve the equation by graphing the related function
\\(\frac{1}{9}x^2 - 9 = 0\\)

select the correct choice below and, if necessary, fill in the answer box to complete your choice

\\(\bigcirc\\) a. \\(x = \square\\) (simplify your answer. use a comma to separate answers as needed.)
\\(\bigcirc\\) b. the solution is not a real number

Explanation:

Step1: Isolate the quadratic term

$\frac{1}{9}x^2 = 9$

Step2: Eliminate the coefficient

$x^2 = 9 \times 9 = 81$

Step3: Take square roots

$x = \pm\sqrt{81} = \pm9$

Answer:

A. $x = 9, -9$
