1 You can create a table of values. Plot y x2 3x 2 on a graph and read off where the curve crosses the x-axis. Determine which form of quadratic equation you have.
0 2 x 3 3 2 x.
Check by inserting your answer in the original equation. The quadratic equation can be written in three different forms. Let y1 ax2 bx c and y2 d. SOLVING QUADRATIC EQUATIONS BY GRAPHING First we have to draw the graph for the given quadratic equation.
