There's nothing else to know I reckon for the Quadratic Equation. Though I will show you how to derive it by Completing the Square (which i will cover in the next post). Another fundamental point that comes out of the Formula, is the b^2 - 4ac, this is called the Discriminant. We shall look it later, it is important because we can determine how a quadratic function may look, and the number and types of roots assosciated with the equation.
