Expert Answer:
Geometrical Interpretation of zeros
It is possible to find the zeros of any polynomial p(x) by just drawing its graph and identifying the points where its graph meets x-axis. The points at which the graph of a polynomial meets x axis are its zeros.
- The number of real zeros of the polynomial is the number of times its graph intersects x axis. A polynomial p(x) of degree n will intersect the x-axis at atmost n points.
- Points where the graph of polynomial touch the x-axis is also the zero of the polynomial.
- A linear polynomial has atmost one real zero.
- A quadratic polynomial has atmost two real zeros.
- A cubic polynomial has atmost three real zeros.
