(3+q)^3+(3+5q)^3 = (3 + q + 3 + 5q)*[(3 + q)² - (3 + q)*(3 + 5q) + (3 + 5q)²] =  = 6*(1 + q)*(9 + 6q + q² - 9 - 18q - 5q² + 9 + 30q + 25q²) =  = 18*(1 + q)*(7q² + 6q + 3) (p-1)^3+(4+4p)^3 = (p - 1 + 4 + 4p)*[(p - 1)² - (p -1)*(4 + 4p) + (4 + 4p)²] = = (5p + 3)*(p² - 2p + 1 - 4p² + 4 + 16 + 32p + 16p²) =  = (5p + 3)*(13p² + 30p + 21)
