\quad \huge \quad \quad \boxed{ \tt \:Answer }


\qquad \tt \rightarrow \: 9w² - 13w + 10

____________________________________


\large \tt Solution \: :


\qquad \tt \rightarrow \: 9 {w}^(2) + (20 {w}^(2) - 15w + 10) + 2w


\qquad \tt \rightarrow \: 9 {w}^(2) + 20 {w}^(2) - 15w + 10+ 2w


\qquad \tt \rightarrow \: 9 {w}^(2) + 20 {w}^(2) - 15w +2w + 10


\qquad \tt \rightarrow \: 29 {w}^(2) - 13w + 10
