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
