-----------------------------------------

5x%2Aroot%283%2C+54x%5E10%29 + 2x%5E2%2Aroot%283%2C+16x%5E7%29 =

= 5x%2Aroot%283%2C+%2827x%5E9%29%2A2x%29 = 2x%5E2%2Aroot%283%2C+%288x%5E6%29%2A2x%29 =

= %285x%29%2A%283x%5E3%29%2Aroot%283%2C+2x%29 + %282x%5E2%29%2A%282x%5E3%29%2Aroot%283%2C2x%29 =

= 15x%5E4%2Aroot%283%2C+2x%29 + 4x%5E5%2Aroot%283%2C+2x%29 =

= %2815x%5E4+%2B+4x%5E5%29%2Aroot%283%2C+2x%29.
