Cubic equation calculator software description
Equation definition
An integral equation that contains only one unknown number (i.e. "element") and the highest degree of the unknown number is 3 (i.e. "degree") is called a cubic equation of one variable (English name: cubic equation of one unknown).
The standard equation of this section
The equation of the form aX^3+bX^2+cX+d=0, (a, b, c, d∈R, and a≠0) is the standard form of a cubic equation of one variable.
Cubic equation calculator calculation method
X1=(Y1)^(1/3)+(Y2)^(1/3);
X2= (Y1)^(1/3)ω+(Y2)^(1/3)ω^2;
X3=(Y1)^(1/3)ω^2+(Y2)^(1/3)ω,
Where ω=(-1+i3^(1/2))/2;
Y(1,2)=-(q/2)±((q/2)^2+(p/3)^3)^(1/2).
Standard cubic equation of one variable aX ^3+bX ^2+cX+d=0, (a, b, c, d∈R, and a≠0).
Let X=Y—b/(3a) be substituted into the above formula.
It can be transformed into a special type of one-dimensional cubic equation Y^3+pY+q=0 that is suitable for direct solution of Cardan's formula.
