$3x^3-9x-10$

$(5x^3-5x-8)-(2x^3+4x+2)$

$cancel(color(red)(5x^3))-5x-8-cancel(color(red)(2x^3))-4x-2$

$3x^3-cancel(color(green)(5x))-8-cancel(color(green)(4x))-2$

$3x^3-9x-cancel(color(blue)(8))-cancel(color(blue)(2))$

$3x^3-9x-10$

How do you write (5x^3 − 5x − 8) − (2x^3 + 4x + 2)(5x^3 − 5x − 8) − (2x^3 + 4x + 2) in standard form?
