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.
Try them
Good luck
