A Walkthrough of Solving a Quadratic Equation
By Tim Fahlberg
This video gives you a quick walkthrough of how to solve a quadratic equation by factoring. Watch how the Zero Product Property comes into play. Remember, if two numbers multiply to equal zero, at least one of the two MUST be zero. It's an important property of our number system, and it is what allows us to solve by factoring.
2.1 Given the vertex and a point find the equation of a parabola - Videos
By Mr. McLogan's Math Channel
http://www.freemathvideos.com In this math tutorial I will show you how to sketch a quadratic function, find the axis of symmetry, determine the y-intercepts and find the zeros or x-intercepts. To find the x-intercepts we use such methods as setting the equation equal to zero and factor, completing the square or using the square root method. For the y-intercept we set x=0 and solve for f(x). The vertex and axis of symmetry can be found by converting the equation from standard form to vertex form by completing the square. I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exaclty how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test

Partial Fraction Decomposion
By The Organic Chemistry Tutor
This precalculus video tutorial provides a basic introduction into partial fraction decomposition. The full version of this video contains plenty of examples and practice problems with repeated linear factors and repeated quadratic factors. Partial fraction decomposition is the process of taking a complex fraction and breaking it into multiple simpler fractions. It's the reverse of adding combining two fractions into a single fraction.

Integration By Partial Fractions
By The Organic Chemistry Tutor
This calculus video tutorial provides a basic introduction into integrating rational functions using the partial fraction decomposition method. Partial fraction decomposition is the process of breaking a single complex fraction into multiple simpler fractions. The integrals of many rational functions lead to a natural log function with absolute value expressions. This video explains what to do when you have repeated linear factors and quadratic factors. This tutorial contains many examples and practice problems on integration by partial fractions.
