Polynomial Roots

Result

x = -((1 - i sqrt(3)) (1/2 (-9 + i sqrt(1419)))^(1/3))/(2 3^(2/3)) - (5 (1 + i sqrt(3)))/(2^(2/3) (3 (-9 + i sqrt(1419)))^(1/3))

x = -((1 + i sqrt(3)) (1/2 (-9 + i sqrt(1419)))^(1/3))/(2 3^(2/3)) - (5 (1 - i sqrt(3)))/(2^(2/3) (3 (-9 + i sqrt(1419)))^(1/3))

x = (1/2 (-9 + i sqrt(1419)))^(1/3)/3^(2/3) + 5/(3/2 (-9 + i sqrt(1419)))^(1/3)
