Løs 3ab^2=10a

$$3 a b ^ { 2 } = 10 a$$

Løs for a (complex solution)

$$\left\{\begin{matrix}\\a=0\text{, }&\text{unconditionally}\\a\in \mathrm{C}\text{, }&b=-\frac{\sqrt{30}}{3}\text{ or }b=\frac{\sqrt{30}}{3}\end{matrix}\right,$$

Vejledning i at løse lineær ligning

Subtraher 10a fra begge sider.

$$3ab^{2}-10a=0$$

Kombiner alle led med a.

$$\left(3b^{2}-10\right)a=0$$

Divider 0 med 3b^{2}-10.

$$a=0$$

Løs for a

$$\left\{\begin{matrix}\\a=0\text{, }&\text{unconditionally}\\a\in \mathrm{R}\text{, }&|b|=\frac{\sqrt{30}}{3}\end{matrix}\right,$$
