    well...it is factorable: x (x (2 x+5)-31)-15. --> this gives you all the zeroes ;) but you're right., it's not easily factorable. graph it :). graphing calculator. otherwise there's nothing...really easy to see besides one

    x (x (2 x+5)-31)-15 --- this is factor? :O

    No need to graph, if you know Newton-raphson or method of bisection.
