Resolver V=3*3t^3-1+27*t^2-1-1*2t^1-1+0

$$V = 3 \times 3 t ^ { 3 - 1 } + 27 \cdot t ^ { 2 - 1 } - 1 \times 2 t ^ { 1 - 1 } + 0$$

Resolver t (complex solution)

$$\left\{\begin{matrix}\\t=-\frac{\sqrt{4V+89}}{6}-\frac{3}{2}\text{, }&\text{unconditionally}\\t=\frac{\sqrt{4V+89}}{6}-\frac{3}{2}\text{, }&V\neq -2\end{matrix}\right.$$

Resolver V

$$V=9t^{2}+27t-2$$

$$t\neq 0$$

Resolver t

$$\left\{\begin{matrix}t=\frac{\sqrt{4V+89}}{6}-\frac{3}{2}\text{, }&V\neq -2\text{ and }V\geq -\frac{89}{4}\\t=-\frac{\sqrt{4V+89}}{6}-\frac{3}{2}\text{, }&V\geq -\frac{89}{4}\end{matrix}\right.$$
