This software solves quadratic equations.
To use it, enter the values of: a, b, and c of the equation you
want to solve, in the corresponding white boxes. For
calculated results, left click on the yellow background or on the
calculation button. |

The above results are rounded to |
|
decimal places. |

You can change the number of decimal places of
X1 and X2 by deleting the blue
number ABOVE, and entering the number of decimal places you prefer.

In this green section, error-checking is
carried out. The values displayed below for
X1 and X2 are NOT rounded down,
because they are used to check for calculation errors, by substituting
into the quadratic equation you entered. |

You can change the number of decimal places
that relate to the error-checking calculations by deleting the blue number
above, and entering the number of decimal places you prefer.
If this number is too large, you will see rounding errors,
consisting of numbers that are almost 0, such as 5.68434e-14
(This number is in scientific notation). |
