Formulas To Memorize

Inline and centered: combining both:

When \(a \ne 0 \), there are two solutions to \(ax^2 + bx + c = 0\) and they are
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$

When $a \ne 0 $, there are two solutions to $ax^2 + bx + c = 0$

And the two solutions are are:

$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$
