Solve d^2x/dt^2+bx=0

$$\frac { d ^ { 2 } x } { d t ^ { 2 } } + b x = 0$$

Solve for b (complex solution)

$$\left\{\begin{matrix}\\b=0\text{, }&\text{unconditionally}\\b\in \mathrm{C}\text{, }&x=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Subtract \frac{\mathrm{d}(x)}{\mathrm{d}t^{2}} from both sides. Anything subtracted from zero gives its negation.

$$bx=-\frac{\mathrm{d}(x)}{\mathrm{d}t^{2}}$$

The equation is in standard form.

$$xb=0$$

Divide 0 by x.

$$b=0$$

Solve for b

$$\left\{\begin{matrix}\\b=0\text{, }&\text{unconditionally}\\b\in \mathrm{R}\text{, }&x=0\end{matrix}\right.$$
