Regroup terms with common powers of xx and do the arithmetic normally.

Explanation:

(color(blue)(4x^3-3x-7)) - (color(red)(3x^3+5x+3))(4x3−3x−7)−(3x3+5x+3)

= (color(blue)(+4x^3) - color(red)(3x^3))+(color(blue)(-3x) - color(red)(5x))+(color(blue)(-7) - color(red)(3))=(+4x3−3x3)+(−3x−5x)+(−7−3)

= x^3 -8x -10=x3−8x−10
