Solve z=u^2v+uv

$$z = u ^ { 2 } v + u v$$

Solve for v (complex solution)

$$\left\{\begin{matrix}v=\frac{z}{u\left(u+1\right)}\text{, }&u\neq -1\text{ and }u\neq 0\\v\in \mathrm{C}\text{, }&\left(u=0\text{ or }u=-1\right)\text{ and }z=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$u^{2}v+uv=z$$

Combine all terms containing v.

$$\left(u^{2}+u\right)v=z$$

Divide both sides by u^{2}+u.

$$\frac{\left(u^{2}+u\right)v}{u^{2}+u}=\frac{z}{u^{2}+u}$$

Dividing by u^{2}+u undoes the multiplication by u^{2}+u.

$$v=\frac{z}{u^{2}+u}$$

Divide z by u^{2}+u.

$$v=\frac{z}{u\left(u+1\right)}$$

Solve for v

$$\left\{\begin{matrix}v=\frac{z}{u\left(u+1\right)}\text{, }&u\neq -1\text{ and }u\neq 0\\v\in \mathrm{R}\text{, }&\left(u=0\text{ or }u=-1\right)\text{ and }z=0\end{matrix}\right.$$

Solve for u (complex solution)

$$\left\{\begin{matrix}u=-\frac{\sqrt{v\left(4z+v\right)}+v}{2v}\text{; }u=-\frac{-\sqrt{v\left(4z+v\right)}+v}{2v}\text{, }&v\neq 0\\u\in \mathrm{C}\text{, }&v=0\text{ and }z=0\end{matrix}\right.$$
