7x^2+15x−12 is divided by x + 3

 

               7x       -  6

x + 3  [    7x^2   +  15x   -   12  ]

               7x^2  +   21x

               __________________ 

                              -6x    -   12

                              -6x    -   18

                             ___________

                                        6   =   remainder
