Hey i would appreciate if someone can guide me on how to factor this:
x^3 + 4x^2 - 2x + 3
I know the answer should be -4.5797, and 0.2899 +- 0.7557i
Any polynomial nth degree can be factorized regardless the nature of its roots...following the well known theorem of algebra.
Kaboose 786 the equation you gave us is a cubic and cannot be solved easily.
you may use a C.A.S to get the roots..There is nothing wrong using math lab or maple...it will help you.
There are some simple qalculators that can be programmed to solve qubic equations as well.
