Understanding Quadratic Equations
Quadratic equations are a type of equation that contains a squared variable. They are often used in fields such as physics, engineering, and finance to model real-world problems. Understanding them is key to mastering mathematics and the Graphing Calculator.
In this section, we will cover the basics.
Definition of Quadratic Equations
A quadratic equation is an equation that can be written in the form of ax² + bx + c = 0, where a, b, and c are coefficients. The variable in this case is x, and the highest power of x is 2 or squared.
Types of Quadratic Equations
There are two types of quadratic equations: standard form and vertex form. Standard form is the form listed above, while vertex form is written as y = a(x – h)² + k.
How to Identify a Quadratic Equation
To identify a quadratic equation, look for the presence of a squared variable (x²) and the absence of any higher powers of x.
