slega [8]

Step-by-step explanation:

{x}^{3}  + 3x + 1 = 1 =  =  =  >  \\  {x}^{3} + 3x = 0 =  =  =  >  \\  x({x}^{2}  + 3) = 0 \\ x = 0 \: or \\  {x}^{2}  + 3 = 0 =  =  =  >  \\  {x}^{2}  =  - 3 =  =  =  > x 1=   \sqrt{ - 3} \: or \: i \sqrt{3}   \\ x2 =  -  \sqrt{ - 3}  =  =  =  > x2 = -  i \sqrt{3}

{x}^{3}  + 3x + 1 = 5 =  =  =  >  \\  {x}^{3} + 3x - 4 =  =  =  > \\  (x - 1)( {x}^{2}   + x + 4) = 0 =  =  =  >  \\ x - 1 = 0 =  =  > x1 = 1 \\  {x}^{2}  + x + 4 = 0 =  =  =  >  \\ x2 =  - 1 + i \sqrt{3}   \\  x3 =  - 1 - i \sqrt{3}

{x}^{3}  + 3x + 1 = 3 =  =  =  >  \\{ x}^{3}  + 3x - 2 = 0 =  =  =  > x = 0.6
