Solving Quadratic Equations by Factoring - MathHelp.com
By yourteachermathhelp
This video is a clip of a smaller segment. Students learn to solve quadratic equations by the method of their choice, using the following rules. If possible, use the factoring method. If there is no coefficient on the squared term, and the middle term of the trinomial is even, use completing the square. If there is a coefficient on the squared term, and/or if the middle term is odd, use the quadratic formula. If the variable only appears in the squared term, get the variable by itself on one side of the equation and square root both sides.
1.4 Finding the zeros of a function - Zeros of polynomial function
By Mr. McLogan's Math Channel
In this video tutorial I show you how to find the zeros of the function. I do this by plugging in zero for the dependent variable, f(x), and then solving for the independent variable (x) using algebra. The methods I use to solve for x include completing the square, factoring, square root method, and quadratic formula.I show how to solve math problems online during a live classroom. 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.

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.

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.
