Pentahelicene

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

Pentahelicene

$\widehat{{\beta }_1}=\frac{\sum (x_i-\overline{x})(y_i-\overline{y})}{\sum (x_i-\overline{x}{)}^2}$; $\widehat{{\beta }_0}=\overline{y}-\widehat{{\beta }_1}\overline{x}$

A more elaborate example of a table

Column heading 1	Column heading 2	Column heading 3
Row heading 1	Cell 2	Cell 3
Row heading A	Cell B	Cell C
