Start with standard form: (y = ax^2 + bx + c)
Factor out (a) from the (x^2) and (x) terms if (a neq 1)
Complete the square inside the parentheses
Add and subtract the same value inside the expression to keep it balanced
Rewrite the trinomial as a perfect square
Simplify to get vertex form: (y = a(x – h)^2 + k)
Identify the vertex as ((h, k))
