The first three steps of completing the square to solve the quadratic equation x2 + 4x - 6 = 0 are shown
below.
Step 1: x2 + 4x = 6
Step 2: x2 + 4x + 4 = 6 + 4
Step 3: (x + 2)^2 = 10
what are the next 3 steps
Step 4: Take the square root of both sides to solve for x + 2: x + 2 = ±√10
Step 5: Solve for x by subtracting 2 from both sides: x = -2 ± √10
Step 6: The two solutions for the quadratic equation x^2 + 4x - 6 = 0 are x = -2 + √10 and x = -2 - √10.
