Im sorry here is the problem rewritten

X^3 -2x^3 + 3x-1 : X^2-x+4

I have to get the sum diff and product and it kicking my tail i think i keep doing it wrong can someone please help me

assuming a typo,

(x^3-2x^2+3x-1)+(x^2-x+4) = x^3-x^2+2x+3
(x^3-2x^2+3x-1)+(x^2-x+4) = x^3-3x^2+4x-5
(x^3-2x^2+3x-1)+(x^2-x+4) = x^5-4x^4+9x^3-12x^2+13x-4

I assume you have no problem with the sum and difference. For details on the product, visit calc101.com and click the "long multiplication" button.
