Graphing Linear Quadratic Systems Worksheets
How to Graph Linear Quadratic Systems We all have studied quadratic equations quite a few times. A quadratic equation is used in many complex problems to simplify them. A quadratic equation can be written as ax 2 + bx + c, where a = 0 To solve a quadratic equation, there are three methods to follow: factoring method, the quadratic formula method, and completing the square method. Factoring - Leaving zero on one side, take all the terms on one side: Now Factor. Set each factor to zero and solve each of these equations. Now make sure that the equation is satisfied by putting the answer in the original equation. Plotting the Equations - We can plot them manually or use a tool like the Function Grapher. To plot them manually: make sure both equations are in "y=" form, choose some x-values that will hopefully be near where the two equations cross over, calculate y-values for those x-values, plot the points and see!
