Answer:
The result is [tex]x = 12[/tex] .
Step-by-step explanation:
If you have [tex]x^2[/tex], then you need to square root both the sides ([tex]x^2[/tex] and [tex]144[/tex]) and get the answer:
[tex]x^2 = 144[/tex]
[tex]\sqrt{x^2} = \sqrt{144}[/tex]
[tex]x = 12[/tex]
So, the answer is [tex]x = 12[/tex] .
