## LaTeX formulae

It is hoped that any serious mathematics content contributor will be thoroughly familiar with LaTeX. Otherwise to generate the text required to display equations, use the CodeCogs LaTeX Equation Generator.

SDIY wiki supports embedding mathematical formulas using $...$ tags.

It can easily be seen, by polynomial expansion, that the following equation is equivalent to the quadratic equation:

${\displaystyle \left(x+{\frac {b}{2a}}\right)^{2}={\frac {b^{2}-4ac}{4a^{2}}}}$

Taking the square root of both sides, and isolating ${\displaystyle x}$, gives:

${\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac\ }}}{2a}}}$
