Answer: a²-2ab + b² + a-b
Step-by-step explanation:
Step 1: Expand the square
(a-b)² + (a-b)
(a-b) (a-b) + (a-b)
Step 2: Distribute
(a-b) (a-b) + (a-b)
a(a-b) - b(a-b) + (a-b)
Step 3: Again distribute
a(a-b) - b(a-b) + (a-b)
a²- ab - b(a-b) + (a-b)
Step 4: One more time distribute
a²- ab - b(a-b) + (a-b)
a² - ab - ab + b² + (a-b)
Step 5: Combine like terms
a²- ab - ab +b² + (a-b)
a²- 2ab + b² + (a-b)
Step 6: Eliminate redundant parentheses
a²- 2ab +b² + (a-b)
a²- 2ab + b² + a-b
