This applet being created in geogebra graphing Calculator app,is mostly compatab;e on android ...[br][br]In this applet you can find the any real or complex and multiple solution of any f(x)=0 if exists... you have to just move the black point (v) to set the initialization to usual Newton rhapson formula x1 = x - f(x)/f'(x) to get solution as red point ... you can set the numver of tterations in the slider of number "itr"
