Question

what are the solution(s) to the quadratic equation $x^2 - 25 = 0$? $x = 5$ and $x = -5$; $x = 25$ and $x = -25$; $x = 125$ and $x = -125$; no real solution

Explanation:

Step1: Isolate the squared term

$x^2 - 25 = 0 \implies x^2 = 25$

Step2: Apply square root property

$x = \pm\sqrt{25} \implies x = \pm5$

Answer:

$x = 5$ and $x = -5$
