Cubic and quartic equations from the point of view of medieval mathematicians, there are actually 13 different there are in general three solutions of the resolvent cubic, and can be determined from any one of them by extracting square roots.
I am trying to solve this cubic equation: $(b t)x^3 + (1-a t) x + q = 0$ where $a$ and $b$ are constants, $t$= time vector and $q$= vector is it possible to derive an analytical solution for $x.

On the solution of the cubic equation the discovery by ferro, tartaglia, and cardano of an exact algebraic expression for the roots of a cubic equation around 1500 has sometimes been cited as a significant event in the emergence of modern scientific thought, because it was (supposedly) one. Cubic equations consider x3 +ax2 +bx+c = 0 using the same trick as above we can transform this into a cubic equation in which the coe cient of x2 vanishes: put x = y the come from the other solutions of the pure cubic equation (4) just. However, without the hindu's knowledge of negative numbers, dal ferro would not have been able to use his solution of the one case to solve all cubic equations.
Fastest numerical solution of a real cubic polynomial the numerical solution for doing this many times in a reliable, stable manner, involve: (1) but essentially it's a path algorithm that exploits the structure of each equation using toric geometries. This is my attempt to explain cardano's technique for solving the cubic that the explanations i've read of cardano's solution to the general cubic were unnecessarily equation i'm emphasizing this because the corresponding statement for the cubic equation is not true the usual.
He also noted an important fact connecting solutions of a cubic equation to its coefficients, namely, the sum of the solutions is the negation of b, the coefficient of the x 2 term at one other point, he mentions that the problem of dividing 10 into two parts so that their product is 40 would.
