WebYou would put the absolute value of the result on the z-axis; when x is real (complex part is 0) the absolute value is equal to the value of the polynomial at that point. The absolute value is always non-negative, and the solutions to the polynomial are located at the points where the absolute value of the result is 0. light\\u0026building messe
