See the attached graph. From the graph the roots of f are approximately -1.9 , -1.2 , 1.1 and 3.

Approximate until the eight decimal places are same.

For x_1=-1.9







Now for x_1=-1.2





Now for x_1=1.1






Now for x_1=3






To eight decimal places the roots of the equation are,

-1.93822883 , -1.21997997 , 1.13929375 , 2.98984102
