ah ha, so this is why you want to divide polynomials

*******______ x^2____________________

(x-2) | x^3 + x^2 - 7 x + 2

********x^3 -2 x^2

********--------------------

************+3 x^2 - 7 x + 2

*******______ x^2_+3x__-1____

(x-2) | x^3 + x^2 - 7 x + 2

********x^3 -2 x^2

********--------------------

************+3 x^2 - 7 x + 2

************+3 x^2 -6 x

************----------------

******************* -1 x + 2

******************* -1 x + 2

*******************-----------

**********Remainder = 0

so

x^2 +3 x - 1
