Here Is the Answer:

4 ± √13.

Step:

To solve the equation x^2 - 8x + 3 = 0 by completing the square, we first move the constant term to the right side of the equation to obtain x^2 - 8x = -3. Then, we take half of the coefficient of x, which is -4, and square it to get 16. We add 16 to both sides of the equation, which gives x^2 - 8x + 16 = 13. The left side of the equation can be factored as (x - 4)^2, which gives us (x - 4)^2 = 13. Finally, we take the square root of both sides to get x - 4 = ±√13, and our solutions are x = 4 ± √13.
