$x^2-6x+13=0$

Using the formula

$x=\frac{+6\pm\sqrt{(36-4\times 1\times 13)}}{2}$

$=\frac{6\pm\sqrt{(-16)}}{2}$

$=\frac{6\pm4i}{2}$

$\therefore x=3\pm2i$.

Your Answer

Surround your text in *italics* or **bold**, to write a math equation use, for example, $x^2+2x+1=0$ or $$\beta^2-1=0$$

Use LaTeX to type formulas and markdown to format text. See example.
