Question

(a-b) (a+b) (b-c) + (b+c) + (c-a) (c+a)​

Answer 1

Answer: (-b³ + b²c + b + c + c² - a² )

Step-by-step explanation:

(a-b) (a+b) (b-c) + (b+c) + (c-a) (c+a)

= (a² + ab - ab - b²)(b-c) + (b+c) + (c² + ac - ac - a²)

= a²b- a²c + ab²- abc - ab² + abc - b³ + b²c + b + c + c² + ac - ac - a²

= -b³ + b²c + b + c + c² - a²
