Subtract 8a²b - 7b² from 5a² - 9ab + 3b² and subtract your result from the sum of the two expressions 4ab² + 3b² - a²b and 2a²b + 7a² - 4ab².
please send full explanation and not only the answer
Those who will do the Answer with proper explanation I will give him/her 5 stars, thanks and a brain list

Step-by-step explanation:
Answer: First Step:
Given: ( 5a² - 9ab + 3b² ) - ( 8a²b - 7b²)
= 5a² - 9ab + 3b² - 8a²b + 7b²
= (5a² - 9ab + 10b² - 8a²b)
2nd Step:
(4ab² + 3b² - a²b) + (2a²b + 7a² - 4ab²)
= 4ab² + 3b² - a²b + 2a²b + 7a² - 4ab²
= (3b² + a²b + 7a²)
3rd Step:
(3b² + a²b + 7a²) - (5a² - 9ab + 10b² - 8a²b)
= 3b² + a²b + 7a² - 5a² + 9ab - 10b² + 8a²b
= -7b² + 9a²b + 2a² + 9ab
Final Answer: -7b² + 9a²b + 2a² + 9ab
