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. 

aX^{2}+bX+C = 0 

a = 


b = 


c = 




The calculated results are presented below, in
red type. 


x_{1}
= 


x_{2}

Discriminant = 




The above results are rounded to 

decimal places. 

You can change the number of decimal places of
X_{1} and X_{2} by deleting the blue
number ABOVE, and entering the number of decimal places you prefer.


In this green section, errorchecking is
carried out. The values displayed below for
X_{1} and X_{2} are NOT rounded down,
because they are used to check for calculation errors, by substituting
into the quadratic equation you entered. 

Not rounded: X_{1}= 


aX_{1}^{2}+bX_{1}+C= 


Not rounded: X_{2}= 


aX_{2}^{2}+bX_{2}+C= 


The above errorchecking is rounded to 

decimal places 

You can change the number of decimal places
that relate to the errorchecking 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 5.68434e14
(This number is in scientific notation).
