Solve the equation x2 3x 10 0 x 2 3 x 10 0 Graph the equation This could either be done by making a table of values as we have done in previous sections or by computer or a graphing calculator The parabola cross the x axis at x 2 and x 5 These are the roots of the quadratic equation We can compare this solution to To graph a quadratic equation, start by solving for h in vertex form, or taking -b divided by 2 times a in standard form. Then, define or calculate the value of k and plot the point (h, k), which is the vertex of your parabola. In the equation, determine whether a is positive, which means the parabola will open upwards, or negative, which means ...

How To Solve Quadratic Equations By Graphing5 years ago. There are multiple ways that you can graph a quadratic. 1) You can create a table of values: pick a value of "x" and calculate "y" to get points and graph the parabola. 2) If the quadratic is factorable, you can use the techniques shown in this video. Three different situations can occur when graphing a quadratic function Case 1 The parabola crosses the x axis at two points An example of this is y x2 x 6 Figure 3 2 1 Looking at the graph we see that the parabola crosses the x axis at x 3 and x 2 We can also find the solutions to the equation x2 x 6 0 by
