Resol 7x=left(x5right)^2*9x

$$7x= { \left(x5 \right) }^{ 2 } \times 9x$$

Resoleu x (complex solution)

$$\left\{\begin{matrix}\\x=0\text{, }&\text{unconditionally}\\x\in \mathrm{C}\text{, }&x_{5}=-\frac{\sqrt{7}}{3}\text{ or }x_{5}=\frac{\sqrt{7}}{3}\end{matrix}\right,$$

Passos per resoldre una equació lineal

Resteu x_{5}^{2}\times 9x en tots dos costats.

$$7x-x_{5}^{2}\times 9x=0$$

Multipliqueu -1 per 9 per obtenir -9.

$$7x-9x_{5}^{2}x=0$$

Combineu tots els termes que continguin x.

$$\left(7-9x_{5}^{2}\right)x=0$$

Dividiu 0 per 7-9x_{5}^{2}.

$$x=0$$
