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 \(f(x) = 0\).

B-spline curve fitting is a powerful mathematical ... B-spline: A type of piecewise polynomial function that is used to create smooth curves and surfaces in computer graphics and geometric modeling.
