Answer 1

$\huge\bold\green{꧁}$$\sf\pink{\fbox{\sf{MsDiplomatic}}}$$\huge\bold\green{꧂}$

=> (2x³ - 6x² + 2x + 5) + (x³ + 4x² - 3x - 3)

=> (2x³ - 6x² + 2x + 5) + x³ + 4x² - 3x - 3

=> (2x³ + x³) + (-6x² + 4x²) + (2x - 3x) + (5 - 3)

=> 3x³ -2x² -1x + 2

=> 3x³ - 2x² - x + 2

With last "-3" cubed

=> (2x³ - 6x² + 2x + 5) + (x³ + 4x² - 3x - 3x³)

=> (2x³ - 6x² + 2x + 5) + x³ + 4x² - 3x - 3x³

=> (2x³ + x³ - 3x³) + (-6x² + 4x²) + (2x - 3x) + 5

=> (3x³ - 3x³) - 6x² + 4x² + 2x - 3x + 5

=> 0 - 2x² -1x + 5

=> -2x² - x + 5
