Includes:
✔ Factoring rules
✔ Quadratic formula
✔ Trig identities
✔ Function transformations
✔ Graphing rules
✔ Common mistakes
⭐ 1. Quadratic Formula: The Foundation
x = (–b ± √(b² – 4ac)) / 2a
Tip: Under exam pressure, write it before solving anything.
⭐ 2. Factoring Shortcuts Every Student Should Know
✔ Take out common factor first
✔ For trinomials:
Multiply a × c → find factors that add to b
⭐ 3. Trigonometry Essentials
SOH–CAH–TOA
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent

⭐ 4. Function Transformations (Most Asked on Tests)
If f(x) → a f(x – h) + k
a = vertical stretch
h = horizontal shift
k = vertical shift
Tip: Positive “h” means shift right — a common misconception.
