F(X) = X^3-X-1， F(1) = -1, F(2) = 5
F(1.5) = 0.875, F(1.25) = -0.296875
F(1.375) = 0.224609375, F(1.3125) = -0.051513671875
F(1.34375)= 0. 082611... , F(1.323125) = -0. 0067833...
F(1.3334375) = 0.037488469..., F(1.32828125) = 0. 01152466...
F(1.325703125) = 0.004205327, F(1.324414) = -0.00129589895
F(1.32506) = 0.0014591518, F(1.32474) = 0.000094..., x = 1.32474
