\(3x^3-4x^2+13x-4\)

\(\left(x^3-2x^2\right)+\left(2x-4\right)-9\)

\(=x^2\left(x-2\right)+2\left(x-2\right)\)

\(=\left(x-2\right)\left(x^2+2\right)-9\)

\(=\left[\sqrt{\left(x-2\right)\left(x^2+2\right)}\right]^2-3^2\)

\(=\left[\sqrt{\left(x-2\right)\left(x^2+2\right)}-3\right]\left[\sqrt{\left(x-2\right)\left(x^2+2\right)}+3\right]\)
