Take the midpoint of the interval (2,3) 2.5, using a calculator be regarded as f (2.5) = -0.084, because f (2.5) f (3) <0, so the zero in the interval (2.5,3).

The interval (2, 3, 2.5 ) with the midpoint Calculator is F (2.5 ) = -0.084 F (2.5 .) because F (3) < 0, the zero point in the interval (2.5 , 3).

Takes the sector (2,3) center point 2.5, is considered as f(2.5)=-0.084. with the calculator because of f(2.5)F(3)<0, therefore zero in sector in (2.5,3).

Taking interval (2,3) of the midpoint of 2.5, use calculator to work f (2.5) =-0.084. because f (2.5), f (3) <0, so zero in the interval (2.5,3).
