Question

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

Explanation:

Step1: Isolate \(x^2\)

Add 25 to both sides: \(x^2 = 25\)

Step2: Take square roots

\(x = \pm\sqrt{25}\), so \(x = 5\) or \(x = -5\)

Answer:

x = 5 and x = -5
