 * __Numerical Estimation of Roots of Polynomials __** There is a formula for finding the roots of a quadratic equation but there are no similar formulae for finding the roots of equations of higher degree. Sometimes the roots can be found by factorisation but at other times this is not possible. On such occasions an approximation to a root can be found by using a numerical method.
