I guess you might as well just use Newton's recursion for these things...
That's why I prefer the approximated result.
Lol.thanks... wow... that looks so complicated lol
The general quintic can be solved in terms of Jacobi theta functions, as was first done by Hermite in 1858. Kronecker subsequently obtained the same solution more simply, and Brioschi also derived the equation.
Yes, I've read very much about Abel.
Very good posts and images uploaded, krassi_holmz. Those would be very useful. BTW, did you know the insolubility of the quintic equation was shown first by Neils Henrik Abel, the Norwegain Mathematician?
this is the exact root!
I am sure you could find this without using the cubic formula.
Equations >4 are unsolvable exactin radicals. (Galoa)
For you question we get:
And quadric equation (useless):
The roots of quadratic equation ax^2+bx+c:
I did not know the roots of a cubic equation and looked for it on the net. I got to this pdf. Ricky, you can find the root of the incomplete cubic equation using the formulae.
If you use the cubic formula, shouldn't you come up with the exact root?
