Given,

$y=f(x)=$

Initial guesses $x_0 =$and$x_1 =$

Error threshold$(e)=$

Solution,

$n$	$x_{n-1}$	$x_{n}$	$x_{n+1}$	$f(x_{n+1})$	$e$
$2$	$1.000$	$2.000$	$1.143$	$-0.507$	$0.857$
$3$	$2.000$	$1.143$	$1.210$	$-0.230$	$0.067$
$4$	$1.143$	$1.210$	$1.265$	$0.024$	$0.055$
$5$	$1.210$	$1.265$	$1.260$	$-0.001$	$0.005$
$6$	$1.265$	$1.260$	$1.260$	$-0.000$	$0.000$

Therefore, the solution is at $x=1.265$
