Step-by-step explanation:

Polynomial

                                      - z³  + 5k⁶  - (-z³ + 10k⁶)

Use law of signs for the parenthesis

                                     - z³  + 5k⁶ + z³  - 10k⁶

Use associative property for like terms

                                    (-z³ + z³) + (5k⁶ - 10k⁶)

Simplify like terms

                                    (0)  +   (-5k⁶)

Result

                                               -5k⁶
