Answer:
-3b² + 22b + ac + bc
Step-by-step explanation:
(a + b)(22 - 3b + c) - (22 - 3b)a
By distribution law,
a(22 - 3b + c) + b(22 - 3b + c) - (22a - 3ab)
22a - 3ab + ac + 22b - 3b² + bc - 22a + 3ab
ac + bc + 22b - 3b²
⇒ -3b² + 22b + ac + bc

Step-by-step explanation:
∴ a(22-3b+c) +b(22-3b+c)-a(22-3b)
∴ 22a-3ab+ac+22b-3b²+bc−22a+3ab
∴ 22a-22a-3ab+3ab+22b-3b²+bc+ac
∴ -3b²+22b +bc+ac
