Long division:   (x³ + 2)  ÷  (x + 1)
                                        <u>    </u><u>x² –  x  +  1   </u>
      x³ + 0x² + 0x + 2      |    x  +  1
   <u>– x³ –   x²</u>    ⋮       ⋮
          –   x² + 0x     ⋮
          <u>+   x² +   x</u><span>     ⋮</span>
                    +  x + 2
<span>                   </span> <u>–  x – 1</u>
                            + 1
         Quotient:   Q(x) = x² – x – 1;
  
     Remainder:   R(x) = + 1.
