Solve d/dx^2=3

$$\frac { d } { d x ^ { 2 } } = 3$$

Solve for d (complex solution)

$$d\neq 0$$

$$x=-\frac{\sqrt{3}}{3}\text{ or }x=\frac{\sqrt{3}}{3}$$

Steps for Solving Linear Equation

Variable d cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by dx^{2}.

$$d=3dx^{2}$$

Subtract 3dx^{2} from both sides.

$$d-3dx^{2}=0$$

Combine all terms containing d.

$$\left(1-3x^{2}\right)d=0$$

Divide 0 by -3x^{2}+1.

$$d=0$$

Variable d cannot be equal to 0.

$$d\in \emptyset$$

Solve for d

$$d\neq 0$$

$$x = \frac{\sqrt{3}}{3} = 0.5773502691896257$$

Solve for x (complex solution)

$$x = -\frac{\sqrt{3}}{3} = -0.5773502691896257$$

$$x=\frac{\sqrt{3}}{3}\text{, }d\neq 0$$

Solve for x

$$x = \frac{\sqrt{3}}{3} = 0.5773502691896257$$

$$x=-\frac{\sqrt{3}}{3}\text{, }d\neq 0$$
