Step 4: Take the square root of both sides to find x + 4: x + 4 = ±√11
Step 5: Solve for x by subtracting 4 from both sides: x = -4 ± √11
Step 6: The solutions to the quadratic equation x^2 + 8x + 5 = 0 are x = -4 + √11 and x = -4 - √11.
The first three steps of completing the square to solve the quadratic equation x? + 8x + 5 = 0 are shown
below.
Step 1:2+82=-5
Step 2: x2 + 8x + 16 = -5 + 16
Step 3: (x + 4)? = 11
