Answer:
Let's simplify step-by-step.
(a−b)(a+b)+b−c+(b−c)(b+c)+(c−a)(c+a)
Distribute:
=(a)(a)+(a)(b)+(−b)(a)+(−b)(b)+b+−c+(b)(b)+(b)(c)+(−c)(b)+(−c)(c)+(c)(c)+(c)(a)+(−a)(c)+(−a)(a)
=a2+ab+−ab+−b2+b+−c+b2+bc+−bc+−c2+c2+ac+−ac+−a2
Combine Like Terms:
=a2+ab+−ab+−b2+b+−c+b2+bc+−bc+−c2+c2+ac+−ac+−a2
=(a2+−a2)+(ab+−ab)+(ac+−ac)+(−b2+b2)+(bc+−bc)+(−c2+c2)+(b)+(−c)
=b+−c
Answer:
=b−c
