X^3+2x^2+3x+4=0 why the value of x is complex number?
So, how do we solve for the complex roots?
One way to solve for the complex roots is to use the cubic formula. By plugging in the coefficients of the polynomial equation, the formula gives the exact values of the three complex roots. However, the formula is very long and complicated, so it's not very practical to use by hand. Another way is to use numerical methods like Newton's method or bisection method to approximate the roots.
