Answer 1

Dude you gotta do FOIL or whatever or just distribute like a normal person, do you know how to do that? If not I'll walk you through it

Answer 2

Yea F.O.I.L. system would work (;
Maybe ur not familiar with that.
Any ways (2ab+−b)(a+3)
(2ab)(a)+(2ab)(3)+(−b)(a)+(−b)(3)
\(2a^{2}\)b+6ab−ab−3b
\(\ 2a^{2}\)b+5ab−3b
