Solving an Equation |
|
|
|
|
|
Let's solve the equation (8x - 2)(3x + 4) = (4x + 3)(6x - 1). We'll use a graphical method. |
|
|
|
|
|
Go to the "Y=" window and put in Y1 = (8x - 2)(3x + 4) and Y2 = (4x + 3)(6x - 1). |
|
|
|
|
|
Graph the function starting off with the standard window (go to "ZOOM" and choose "ZoomStd." |
|
|
|
|
|
This picture is not very helpful so we will change our window some. Use the settings shown to the right. |
|
|
|
|
|
Press <u>"GRAPH." |
|
|
|
|
|
The two graphs seem to cross somewhere in the first quadrant. We'll resize the window again. Use the settings to the right. |
|
|
|
|
|
Press <u>"GRAPH." |
