$y = - x^{3} - 31 x^{2} - 239 x - 730$ $color(magenta)(y=-x^3-31x^2-239x-730$

Explanation:

$y = {(- x - 9)}^{3} - {(2 x - 1)}^{2}$ $y=(-x-9)^3-(2x-1)^2$

$y = - x^{3} - 27 x^{2} - 243 x - 729 - (4 x^{2} - 4 x + 1)$ $y=-x^3-27x^2-243x-729-(4x^2-4x+1)$

$y = - x^{3} - 31 x^{2} - 239 x - 730$ $color(magenta)(y=-x^3-31x^2-239x-730$
