Quadratics are equations that involve a variable raised to the power of 2.
They have three parts: $a,b,\text{ and }c$.
$a$ determines how steep or flat the curve is, $b$ shifts the curve horizontally, and $c$ affects its vertical position.
By solving quadratics, we find values for the variable that make the equation true.
These equations are used in areas like physics and engineering to solve problems involving motion and relationships.

Quadratic functions involve a variable squared, represented by an equation of the form $f(x)=a{x}^2+bx+c$
They create a curved line called a parabola when graphed. The coefficient $a$ determines whether the parabola opens upward or downward.
The constants $b$ and $c$ affect the position of the parabola.

Graphing a quadratic function using transformations is a method that starts with the basic form of a quadratic equation and then applies shifts, stretches or compressions, and reflections to graph the given quadratic function.

Writing a quadratic function using transformations involves starting with the standard form of a quadratic function and then applying various transformations like vertical shifts, horizontal shifts, vertical stretches or compressions, and reflections to create a new quadratic function.

Completing the square is a technique used to rewrite a quadratic equation in standard form into its vertex form.
This method is particularly useful for solving quadratic equations, graphing quadratic functions, and analyzing their properties.

The square root principle is foundational for solving quadratic equations, especially those that can be easily rearranged into a form where one side of the equation is a perfect square.
It's also a key concept in understanding the properties of quadratic functions and their graphs, as it relates directly to finding the x-intercepts or zeros of the function.

Graphing provides a visual way to understand the solutions of a quadratic equation, especially helpful for identifying the number of real solutions and getting an approximate value for those solutions.

Factoring is an elegant method for solving quadratics when applicable, but it's worth noting that not all quadratic equations can be easily factored, especially if they have irrational or complex roots.
In such cases, other methods like completing the square, using the quadratic formula, or graphing may be more appropriate.

The quadratic formula is particularly useful because it can be applied to any quadratic equation, regardless of whether it can be easily factored or not.

Quadratics are used in math, science, and engineering to solve various problems and find important points on graphs and are used to describe real-life situations and solve problems involving maximum or minimum values.
They help us understand and analyze various phenomena in fields like physics, business, and engineering.
