Complete the Square
Add $1 \times 1$ tiles to form a perfect square.
Tiles placed: {{ s1_grid.filter(Boolean).length }} / {{ (s1_b/2)**2 }}
The Discriminant (Δ)
Adjust to make the parabola touch the axis exactly once.
Discriminant (Δ = b² - 4ac)
{{ s2_delta }}
{{ s2_delta > 0 ? '2 Real Roots' : (s2_delta === 0 ? '1 Repeated Root' : '0 Real Roots') }}
b = {{ s2_b }}
c = {{ s2_c }}
