$- 7 x^{3} - x^{2} + 2 x - 11$ $-7x^3-x^2+2x-11$

Explanation:

Given -

$(- 3 x^{3} + x - 11) - (4 x^{3} + x^{2} - x)$ $(-3x^3+x-11)-(4x^3+x^2-x)$

First remove the brackets.

$- 3 x^{3} + x - 11 - 4 x^{3} - x^{2} + x$ $-3x^3+x-11-4x^3-x^2+x$

Then simplify by collecting the like terms together.

$- 7 x^{3} - x^{2} + 2 x - 11$ $-7x^3-x^2+2x-11$
