Answer 1

Step-by-step explanation:

${3a}^{2} \div a-(5a + 3a - a + b - 2a + 3b) \\ {3a}^{2} \div a(7a + b + a) \\ 3a - (8a + b) \\ 3a - 8a - b \\ - 5a - b$

I hope it will be correcte answer.

Mark me brainliast point when it will correct answer.

I have no any brainliast point.

Answer 2

Step-by-step explanation:

1. 3a^2/a(5a+3a+a+b-2a+3a)
2. 3a^2*1/a(10a-b)
3. 3a^2*9a-b

=30a^2-b
