First, we need to find which number when substituted into the equation will give the answer zero. \(f(1) = {(1)^3} + 4{(1)^2} + (1) - 6 = 0\) Therefore \((x - 1)\)is ...

In the cubic case, this is identical to (3.4). The Bernstein polynomials of degree four are shown in Figure 4.2. The control polygons in the figure are explained in a more thorough discussion of ...
