Question

find the solution for the equation using a table.
$2x^2 - 128 = 0$
select the correct choice below and, if necessary, fill in the answer box to complete your choice.
a. the solution(s) is/are $x = \square$.
(type an integer or a decimal. use a comma to separate answers as needed.)
b. the equation has no solution.

Explanation:

Step1: Isolate the $x^2$ term

Add 128 to both sides:
$2x^2 = 128$

Step2: Solve for $x^2$

Divide both sides by 2:
$x^2 = \frac{128}{2} = 64$

Step3: Solve for x

Take square root of both sides:
$x = \pm\sqrt{64} = \pm8$

Answer:

A. The solution(s) is/are x = 8, -8
