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] .
