Answer:
x=8 is a true solution of the radical equation
Explanation:
we have

Solve for x
squared both sides

Convert to factored form

The solutions are x=2 and x=8
Verify the solutions
For x=2
Substitute in the original equation

----> is not true
therefore
x=2 is not a true solution of the radical equation
For x=8
Substitute in the original equation

----> is true
therefore
x=8 is a true solution of the radical equation
