See your answer below.

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
