(x^3-5x^2+7x-12)/(x-4) 

 

 

           x^2  -  x     +  3

x - 4 [ x^3  -5x^2  +  7x  -12  ] 

          x^3  -4x^2

         ___________________

                  -x^2   +  7x

                  -x^2  +   4x

                  ______________

                              3x   -  12

Polynomial long division:

\(\begin{array}{|rcll|} \hline \dfrac{x^3-5x^2+7x-12}{x-4} &=& x^2-x+3 \\ \hline \end{array}\)
