Solve x2 - 8x = 3 by completing the square. Which is the solution set of the equation?

A. (4 - √19, 4 + √19)
B. (4 - √11, 4 + √11)
C. (4 - √8, 4 + √8)
D. (4 - √3, 4 + √3)

Answer 1

A

Explanation:

because when doing these equations it is the same except one is positive and one is negative

Answer 2

A.

Explanation:

Step 1: Write equation

x² - 8x = 3

Step 2: Solve for x

1. Complete the Square: x² - 8x + 16 = 3 + 16
2. Factor: (x - 4)² = 19
3. Square root both sides: x - 4 = ±√19
4. Add 4 to both sides: x = 4 ± √19
