Online calculator which helps you in solving the complex roots (2nd order polynomial).
Complex roots is the result of solving quadratic equations with complex coefficients of the form: (a x X2 + b x X + c = 0).
Make the solution in two consecutive steps, the first step according to the formula (D = b2 – 4 x a x c) calculate the discriminant, then
according to the formula (X 1,2 = (- b +- (sqrt (D)) / 2 x a) calculates the roots and coefficients (a,b,c) and discriminant (D) are complex numbers.
The necessity to calculate complex roots is a popular problem not only in mathematics but also in physics in solving various problems, and electrical engineering in the study of AC single-phase and three-phase current.
