Answer 1

Answer:

mark me as brainliest

Step-by-step explanation:

1 - x - x^2 + x^3 = x^3 -x^2 -x +1

   $x^3 -x^2 -x +1$

-  $2x^3 - 3x^2 +4x - 13$

= $x^3-2x^2+3x-12$

Answer 2

$\mathfrak{\huge \underline{Question:}}$

$Subtract ~1 - x-x^2+x^3~from~ 2x^3-3x^2+4x-13$

$\mathfrak{\huge \underline{Answer:}}$

$2x^3-3x^2+4x-13-(1 - x-x^2+x^3) \\\\ = 2x^3-3x^2+4x-13-1+x+x^2-x^3 \\\\ = 2x^3-x^3-3x^2+x^2+4x+x-13-1 \\\\ = \boxed {x^3-2x^2+5x-14}$
