We've seen linear and exponential functions, and now we're ready for quadratic functions. We'll explore how these functions and the parabolas they produce can be used to solve real-world problems.

This topic covers: - Solving quadratic equations - Graphing quadratic functions - Features of quadratic functions - Quadratic equations/functions word problems - Systems of quadratic equations - …

Gain more insight into the quadratic formula and how it is used in quadratic equations. The quadratic formula helps you solve quadratic equations, and is probably one of the top five formulas in math.

In this video I want to do a bunch of examples of factoring a second degree polynomial, which is often called a quadratic. Sometimes a quadratic polynomial, or just a quadratic itself, or quadratic …

The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√ …

And what's neat about this is that this will work for any quadratic equation, and it's actually the basis for the quadratic formula. And in the next video or the video after that I'll prove the quadratic formula …
