Frequently Asked Questions
How are complex/imaginary roots represented?
Roots containing square roots of negative numbers are solved as complex numbers and written in the standard formatting a + bi.
Does coefficient "a" support zero value?
For quadratic systems, "a" must be non-zero to execute. Setting "a" to zero reduces the equation to a linear or sub-degree relationship.
