How to factorize x^4 + x^3 + 2.01 x^2 + 0.01 x + 0.01 = 0?

  1. Jan 17, 2010 #1
    I need to get this into (x^2+ x + const) * (x^2+ x + const) format, the answer for this equation is (x^2+x+2)*(x^2+0.0025x+0.005)... I dont know how to get there, NEED HELP EXAM DAY AFTER!!

    Hi logix88! :smile:

    (try using the X2 tag just above the Reply box :wink:)
    I don't get it :redface:

    (x2+x+2)*(x2+0.0025x+0.005) quite obviously starts x4 + 1.0025x3 + … , not x4 + x3 + …

    it is correct to 2dp (decimal places)

    (x^2+x+2)*(x^2+0.0025x+0.005) is also clearly not in (x^2+ x + const) * (x^2+ x + const) format.
