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.
Parabola Equations - Graphing Parabolas - YourTeacher.com
By yourteachermathhelp
For a complete lesson on parabola equations and graphing parabolas, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to graph quadratic equations that are written in y -- k = a(x -- h)2 form by using the coordinates (h, k) to graph the vertex, and using the x and y-intercepts to graph the parabola. Students are reminded that to find the y-intercept, they must substitute a 0 in for x, and to find the x-intercept(s), they must substitute a zero in for y. Students are also asked to find the axis of symmetry using the formula x = h.
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
