PLEASE HELP!!!! PLEASEEE!!
What are all methods to finding zeros and factors of higher degree polynomial functions?
Use f(x)=3x^4+2x^3x^2+6x+8 to explain

Best ResponseYou've already chosen the best response.1I'm not sure about all the methods . This is equation of 4th degree so there are 4 roots The rational root theorem will give you an idea about the possible roots. You multiply the first coefficient by the last  in this case its 3*8 = 24 so the possible roots are factors of 24 +/1 , +/ 2 , +/3,+/ 4,+/ 6 , +/ 8 , +/ 12

Best ResponseYou've already chosen the best response.1There is a general solution for 4th degree polynomials, but nothing higher. It is not fun but you can read about it. Set aside some time:)

Best ResponseYou've already chosen the best response.1you might try all the rational roots i mentioned and none will fit the 4 roots may be all complex

Best ResponseYou've already chosen the best response.1I would use wolframalpha or a calculator and while you save time on doing a bunch of calculations and depressing cubics...you can learn about the history of the general formulas to the cubic and 4th degree polynomials. The history is fascinating and has stealing, cheating, lying, throwing bottles, and general greatness.
