Question

Use synthetic division to divide (x3 + x2 – 40x – 4) ÷ (x – 6).   

A. x2 + 7x + 2 R 8   B. x3 + 6x – 1 R 2   C. x2 – 7x + 3 R 5   D. x2 + 5x – 2 R 6

Use synthetic division to divide (3y3 – 9y2 – 56y + 8) ÷ (y – 6).
    
  A. y2 + y – 1 R 11
  B. 3y2 + 9y – 2 R -4
  C. 3y2 – 9y + 4 R 10
  D. 2y2 – 2y + 8 R 9

Answer 1

6 | 1 1 -40 -4
. | 6 42 12
- - - - - - - - - - - - - -
. | 1 7 2 8


`(x^3+x^2-40x-4)/(x-6)=x^2+7x+2\text{ R }8`

6 | 3 -9 -56 8
. | 18 54 -12
- - - - - - - - - - - - - - -
. | 3 9 -2 -4


`(3y^3-9y^2-56y+8)/(y-6)=3y^2+9y-2\text{ R }-4`
