Question

solve the equation for n.
$n^2 - 144 = 0$
show your work here
$n = $

Explanation:

Step1: Isolate \( n^2 \)

Add 144 to both sides of the equation \( n^2 - 144 = 0 \) to get \( n^2 = 144 \).

Step2: Take square root

Take the square root of both sides. Remember that a square root has two solutions (positive and negative), so \( n = \pm\sqrt{144} \).

Step3: Calculate square root

Since \( \sqrt{144} = 12 \), we have \( n = \pm 12 \).

Answer:

\( n = 12 \) or \( n = -12 \)
