Answer:

12 and (-12)

Step-by-step explanation:

Solve for x.

x^2= 144

square root both sides and get,

x= 12

and

x= (-12)

remember to put your negative and 12 into parenthesis because you are multiplying the negative as well.

Answer:

x = 12

x = -12

Step-by-step explanation:

Step 1: Take the square root of both sides.

  • [tex]\sqrt{x^2} =[/tex] ± [tex]\sqrt{144}[/tex]
  • [tex]x =[/tex] ± [tex]\sqrt{144}[/tex]
  • [tex]x = 12[/tex] or [tex]x = -12[/tex]

Therefore, x = 12 and x = -12 are the answers.
