You have to reverse the foil

That is all i can give you

it is a triple foil

example: (x+/-3)(x+/-3)(x+/-3)

So we have

(2x^3 - x^2- 9x+18) \ (x-1)

Let's do some "long division" on this one...we have

2x^2 + x - 8

__________________x - 1 ) 2x^3 - x^2- 9x+18

2x*3 - 2x^2

_________________

x^2 - 9x

x^2 -   x

_________

-8x + 18

-8x + 8

_______

10

So we have

2x^2 + x - 8 with a "remainder" of 10 / (x-1)

P.S.......I don't if this is gonna' line up correctly on this new website, but I did my best !!!

Let me try this again !!! (There is no "preview," so I can't tell what might happen!!)

2x^2 + x - 8

__________________

x - 1 ) 2x^3 - x^2- 9x+18

2x*3 - 2x^2

_________________

x^2 - 9x

x^2 -   x

_________

-8x + 18

-8x + 8

_______

10

Re: (2x cube - x square- 9x+18) \(x-1)

the division sign is a round the wrong way.  I assume that this is just a typo.
