Solving polynomials We solve polynomials algebraically in order to determine the roots - where a curve cuts the x -axis. A root of a polynomial function, f (x), is a value for x for which f (x) = 0.

That formula, x = –b± b2–4ac√ 2a, tells you how to find the roots, or the values of x that make an expression equal to zero, of the second-degree polynomial ax2 + bx + c. Over time, mathematicians ...

The nature and co-ordinates of roots can be determined using the discriminant and solving polynomials as part of Bitesize Higher Maths ...

We present an elementary topological proof that the roots of a polynomial vary continuously as a function of the coefficients. This monthly journal, begun in 1950, is devoted entirely to research in ...
