     3.1x^3 - 2.4x^2 + 6x - 3 = 4x^2 + 3x + 2

     3.1x^3 - 6.4x^2 + 3x - 5 =  0

     Real solution:

     x ≈ 1.98614

     Complex solutions:

     x = 0.0391873 - 0.900302 i

     x = 0.0391873 + 0.900302 i

    1st multiply by 10 :.... 31 x³ - 24 x² + 60 x - 30 = 40 x² + 30 x + 20 ---->

    31 x³ - 64 x² + 30 x - 50 = 0...only real solution ≈1.986...use Newton's techniques with starting value x = 2
