you have provided only afunctionwhich can not have a root. i suppose you wanted to say the roots of the. in that case, the graph will be like this:-http://www4d.wolframalpha.com/Calcul...20&w=300&h=187equation

clearly, you get the solutions from ,ie, and

thus,the equation has 3 roots, 2 of which are 0, and the third one is
