Completing The Square - Plotting Quadratics

This video tutorial explains how completing the square simplifies graphing quadratics. It covers identifying key points like where the curve crosses the axes and the vertex, which is the turning point. The video provides practice problems and emphasizes the importance of changing the sign of the first number while keeping the second the same when identifying the vertex. It concludes with tips and encourages viewers to engage with the content.
