Remainder theorem to find the remainder when f(x) is divided by the given x-k

f(x)=x^3-4x^2+2x+4; x+2

2 x -4 2 4

1 2 -4 4

1 -2 -2 8

2)x^3-4x^2+2x+4. (X^3-2x^2-2x) is the answer

x^3 -2x^2+-2x

-2x^2+4x

6x+4

-2x+4

8x+8

I'm not sure the bottom is right

**Steve**, Wednesday, March 20, 2013 at 3:56pmIf you are dividing by x+2, the remainder cannot be 8x+8

The remainder theorem says that the remainder when dividing by (x-a) is f(a)

f(-2) = -8 - 4(4) + 2(-2) + 4 = -24
