What is the answer to this radical equation

x = 36

Step-by-step explanation:

Given

= 7 ( square both sides )

( )² = 7²

x + 13 = 49 ( subtract 13 from both sides )

x = 36

To solve the radical equation, completing the square all whole equation.

As defined,

Therefore,  (Although Absolute Function gives 2 conditions, however - domain of radical function must be greater than or equal to 0. Meaning x < 0 for another condition doesn't apply.)

Move 13 to subtract.

Therefore, the answer is x = 36.
