STAMPED · NIGHT 1 BACK
built by a student who has sat locked out of a board
Who
Lena Park, 16, 11th grade Algebra 2. Nine school days of flu. First night back. Westfield High, Period 3, Worksheet 4.3, 11:14 PM.
The lockout
The page treats (b/2)², √(−1), and i as already in her hands. She still has last month’s algebra. The next line is unreadable.
What changed
Twelve minutes. Three marks defined. She writes the first move of problem 2. Relink does not.

Worksheet 4.3 — Completing the Square
Use the same moves as the example. Show every step. Leave answers in exact form.
Example — already on the board
Solve x² + 6x + 10 = 0
x² + 6x = −10
x² + 6x + 9 = −1
the packet writes: add (b/2)²
(x + 3)² = −1
x + 3 = ±√(−1)
x + 3 = ±i
x = −3 ± i
Now you try
2. x² + 8x + 20 = 0
3. x² − 4x + 13 = 0
After · same page, she wrote the next line

Worksheet 4.3 — Completing the Square
Use the same moves as the example. Show every step. Leave answers in exact form.
Example — already on the board
Solve x² + 6x + 10 = 0
x² + 6x = −10
x² + 6x + 9 = −1
half of 6, then square → 9. Makes (x + 3)².
the packet writes: add (b/2)²
(x + 3)² = −1
x + 3 = ±√(−1)
the square may equal a negative; write ±√(−1) and continue.
x + 3 = ±i
i names √(−1). Two answers: −3 + i and −3 − i.
x = −3 ± i
Now you try
2. x² + 8x + 20 = 0
x² + 8x = −20
3. x² − 4x + 13 = 0
