Final answer:
The equation √x²-8 = 2 can be solved by adding 8 to both sides, squaring both sides, and then taking the square root. The solution is x = -10 or x = 10.
Step-by-step explanation:
To solve the equation √x²-8 = 2, we need to isolate the variable x. First, we add 8 to both sides of the equation to get √x² = 10. Then, we square both sides of the equation to eliminate the square root, resulting in x² = 100. Taking the square root of both sides gives us x = ±10. Therefore, the solution to the equation is x = -10 or x = 10.
