Solve 8x^2div7x9=3

$$8 { x }^{ 2 } \div 7x9=3$$

Solve for x_9

$$x_{9}=\frac{21}{8x^{2}}$$

$$x\neq 0$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 7.

$$8x^{2}x_{9}=21$$

Divide both sides by 8x^{2}.

$$\frac{8x^{2}x_{9}}{8x^{2}}=\frac{21}{8x^{2}}$$

Dividing by 8x^{2} undoes the multiplication by 8x^{2}.

$$x_{9}=\frac{21}{8x^{2}}$$

Solve for x (complex solution)

$$x=-\frac{\sqrt{42}x_{9}^{-\frac{1}{2}}}{4}$$

$$x=\frac{\sqrt{42}x_{9}^{-\frac{1}{2}}}{4}\text{, }x_{9}\neq 0$$

Solve for x

$$x=\frac{\sqrt{\frac{42}{x_{9}}}}{4}$$

$$x=-\frac{\sqrt{\frac{42}{x_{9}}}}{4}\text{, }x_{9}>0$$
