Solve for [tex]x[/tex].

[tex]x^2 - 5 = 139[/tex]

Answer :

To solve the equation [tex]\( x^2 - 5 = 139 \)[/tex], we'll follow these steps:

1. Add 5 to both sides:
We want to isolate [tex]\( x^2 \)[/tex] on one side, so we'll add 5 to both sides of the equation.
[tex]\[
x^2 - 5 + 5 = 139 + 5
\][/tex]
Simplifying gives:
[tex]\[
x^2 = 144
\][/tex]

2. Take the square root of both sides:
To find [tex]\( x \)[/tex], we take the square root of both sides of the equation.
[tex]\[
x = \sqrt{144}
\][/tex]

3. Calculate the square root:
The square root of 144 is 12.
[tex]\[
x = 12
\][/tex]

So, the solution to the equation [tex]\( x^2 - 5 = 139 \)[/tex] is [tex]\( x = 12 \)[/tex].
