Question

find the solutions to the equation below. check all that apply. $x^{2}-25 = 0$ a. $x=-1$ b. $x = 1$ c. $x=-3$ d. $x=-5$ e. $x = 5$ f. $x = 3$

Explanation:

Step1: Isolate the squared term

Add 25 to both sides of $x^{2}-25 = 0$, getting $x^{2}=25$.

Step2: Take square - root of both sides

$x=\pm\sqrt{25}$, so $x = 5$ or $x=-5$.

Answer:

D. $x = - 5$, E. $x = 5$
