Vertex Form: y = a(x-h)² + k
Completing the square is a method used to solve quadratic equations and convert them into vertex form. Here's the general process:
1️⃣ Start with the standard form: ax² + bx + c = 0
2️⃣ Move the constant to the right side: ax² + bx = -c
3️⃣ Divide by a (if a ≠ 1) to make the leading coefficient 1
4️⃣ Add (b/2)² to both sides to create a perfect square trinomial
5️⃣ Factor the left side as a perfect square: (x + b/2)²
6️⃣ Simplify the right side and write in vertex form: y = a(x - h)² + k
y = a(x - h)² + k
h = -b/(2a)k = f(h)
Δ = b² - 4ac
x = (-b ± √Δ) / 2a
