I find intersection points of two circles, determine all roots of cubic and quartic equations including real and complex values, and show how to draw the roots neatly on a single Argand diagram. I also cover solving another cubic from shared roots, and a separate equilateral triangle problem using rotations and coordinates to get exact area. Finally I work out a polar coordinate locus and a shaded region area. There is no specific action requested from viewers."}
