solving systems of linear and quadratic equations

#SOLVING SYSTEMS OF LINEAR AND QUADRATIC EQUATIONS FREE#

To solve a quadratic equation by factoring, Put all terms on one side of the equal sign, leaving zero on the other.

There are three basic methods for solving quadratic equations: factoring, using the quadratic formula, and completing the square. These solutions also represent the points of intersection of the graphs of the equations. A quadratic equation is an equation that could be written as ax 2 + bx + c 0 when a 0. Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more.

Use the substitution method described earlier for solving systems of linear equations in two variables. Explore math with our beautiful, free online graphing calculator. Solve Nonlinear Systems of Equations in Two Variables by Substitution The point(s) of intersection of the graphs have coordinates that will satisfy the system of equations. We will discuss solving linear and quadratic equations as well as applications. The ability to solve equations and inequalities is vital to surviving this class and many of the later math classes you might take. Graph each equation (as described earlier) on one set of axes. In this chapter we will look at one of the most important topics of the class.

The graph is a V-shape so you must use enough ordered pairs so that you can find the lowest point of the V. Plot points that satisfy the equation (as described earlier).

In conclusion this slide pack can be used not only to solve a system of linear and quadratic equations, but is excellent for a review of linear equations in SIF and general quadratic equations.Solving Systems of Linear Equations in Two Variables Using the Addition/Elimination Method: I use this presentation in my Math 2/Algebra 2 class and I provide them with a hard-copy of the slides so they can follow along during the presentation and make notes as required on the slides. Several examples are provided to demonstrate the steps to solve linear equations, quadratic equations and a system of both types of equations.Ī total of 26 highly animated slides are included in this presentation and the native MS PPT file is included so that the teacher may modify them as desired. The detailed steps to solve this system of equations with or without a graphing calculator are provided as well as the use of substitution to algebraically solve the system of equations is provided. The third and final portion of the slide pack combines the concepts for both linear and quadratic equations in the form of a system of both of these types of equations. The second part of the presentation materials includes a review of the basic structure and graphing of quadratic equations. The slide pack initially includes a detailed review of the structure and graphing of linear equations in slope intercept form (SIF) with and without the use of a graphing calculator. The presentation is comprised of three (3) parts. This Microsoft PPT presentation reviews the detailed steps required to solve linear and quadratic systems of equations with and without a graphing calculator.
