10x%5E3%28x-3%29-5x%28x-3%29=0
%2810x%5E3-5x%29%28x-3%29=0
5x%282x%5E2-1%29%28x-3%29=0
solutions:

if 5x=0...->...x=0

if 2x%5E2-1=0...->...2x%5E2=1->...x=sqrt%281%2F2%29=1%2Fsqrt%282%29..->

x=1%2Fsqrt%282%29=1%2F1.41=0.709 or x=-1%2Fsqrt%282%29=-1%2F1.41=-0.709
so,x=0.709 or x=-0.709

if x-3=0..->...x=3
