Cubic equation is 3rd order equation so it has 3 solution. one universal method to solve any polynomial equation is to plot it on the graph, points where curve intersect x axis is your solutions. another useful method is hit and trial guess one root, most of the times it is in between (-1) to 1( questions which are given to students to solve in examination hall), some other numerical method techniques are also available as options. you can try python programming to solve equation by numerical methods. Hope it helps.
