I'm just going to give a little hint there's a subtraction sight in front of a grouping symbol which means it's a roadblock a roadblock is a word that means do the opposite which means u have to do the opposite inside of the second grouping symbol.ex.-(3m+2),the 3m would become negative and the +2 would become a -2 then you can distribute

I learned this and it helped me hopefully it helps u to!!
