Geometrical Meaning of Zeroes of a Polynomial

The video tutorial explains how to find the zeros of polynomials using graphs. It starts with linear polynomials, showing how to plot them and identify zeros where the graph intersects the X-axis. The tutorial then moves to quadratic polynomials, illustrating the U-shaped parabola and its zeros. Finally, it covers cubic polynomials, describing their S-shaped graphs and zeros. The video concludes with an analysis of various polynomial graphs, emphasizing the relationship between graph shapes and the number of zeros.
