Question

what is the geometrical meaning of the zeroes of the polynomial

Answer 1

Geometrical Meaning of the Zeroes of a Polynomial. Any real number m is a zero of a polynomial p(x) if p(m) = 0. Let us consider the geometric representation of linear and quadratic polynomials and the meaning of their zeroes.  Hence the zero of x + y = 7 is (7,0) as it intersects the x-axis at (7, 0).

Answer 2

it is the value where the graph of polynomial touches or cuts the x axis
