For this case we have the following equation:
[tex]x^2 = 169[/tex]
What we must do for this case is to clear the value of x.
To do this, remember that when clearing you have two solutions.
A solution is positive.
A solution is negative.
We have then:
[tex]x = +/- \sqrt{169}
x = +/- 13 [/tex]
Therefore, the solutions are:
[tex]x1 = 13
x2 = -13[/tex]
Answer:
the solutions to the equation are:
[tex]x1 = 13 x2 = -13[/tex]
