Quintic equation roots
Returns all the roots of a quintic equation with a real or complex number coefficient.
\(\small{a*x^5+b*x^4+c*x^3+d*x^2+e*x+f=0}\)
Note 1: It should be \(a\ne0\)
Note 2: If the coefficient is a real number, the real number will be written in the first box, the second box will be zero, if the coefficient is a complex number, the real part of the number will be written in the first box, and the virtual or image part will be written in the second box.
