Answer 1

divide it you will get the correct answer

Answer 2

Answer:

x² + x -6 ) x³ - 3x² -12x  + 19 ( x -4

                x³ + x² -6x

    --------------------------------

              -4x² -6x + 19 

              -4x²-4x + 24 

-------------------------------------

                   -2x - 5 

hence ,

   x³ - 3x² -12x + 19 = (x² +x - 6)(x - 4) -(2x + 5)

   x³ - 3x² -12x + 19 + (2x + 5)  = (x² + x - 6)(x - 4)

hence if we add (2x + 5)
