Numerical Solution of Polynomial Equations
cannot find solutions in terms of radicals to polynomial equations, it returns a symbolic form of the result in terms of Root
You can get numerical solutions by applying N
This gives the numerical solutions to 25-digit precision.
You can use NSolve
to get numerical solutions to polynomial equations directly, without first trying to find exact results.
