Answer 1

Step-by-step explanation:

1st bracket work , then second bracket , then 3rd bracket work

Answer 2

Answer:

-6a²-2ab+3a-6b

Step-by-step explanation:

Simplification:

-3a²-[5ab+3{a²-(ab-b)-(a-b)}]

= -3a²-[5ab+3{ a²-ab+b-a+b }]

= -3a²-[5ab+3{ a²-ab-a+2b}]

= -3a²-[5ab+3(a²)+3(-ab)+3(-a)+3(2b)]

= -3a²-[5ab+3a²-3ab-3a+6b]

= -3a²-[3a²+2ab-3a+6b]

= -3a²-3a²-2ab+3a-6b

= -6a²-2ab+3a-6b
