Step-by-step explanation:

\tt{(6 {x}^{3} + 3 {x}^{2} + 3) + (2 {x}^{3} - 5x + 1)   }

Remove the unnecessary parentheses

⟢ \tt{6 {x}^{3}  + 3 {x}^{2}  + 3 + 2 {x}^{3} - 5x + 1 }

Combine like terms. Like terms are those which have the same base. Remember that only coefficients of like terms can be added or subtracted and their bases remains the same.

⟢ \tt{6 {x}^{3}  + 2 {x}^{3}  +3 {x}^{2}  + 3 + 1 - 5x}

⟢ \tt{8 {x}^{3}  + 3 {x}^{2}  + 4 - 5x}

In standard form , the expression should be written in a way that power of variables goes from highest to lowest.

\red{ \boxed{ \boxed{ \tt{Our \: final \: answer :  \boxed {\underline{ \tt{8 {x}^{3}  + 3 {x}^{2}  - 5x + 4}}}}}}}
