Answer 2

Given :-

$\begin{gathered}\\ \large\dashrightarrow\mathsf {(2x + 3x {}^{2} + 8) + (5x {}^{2} + 3x + 5) } \\ \end{gathered}$

Solution :-

$\begin{gathered}\\ \large\dashrightarrow\mathsf {2x + 3x {}^{2} + 8 + (5x {}^{2} + 3x + 5) } \\ \end{gathered}$

$\begin{gathered}\\ \large\dashrightarrow\mathsf {2x + 3x {}^{2} + 8 + 5x {}^{2} + 3x + 5 } \\ \end{gathered}$

$\begin{gathered}\\ \large\dashrightarrow\mathsf {5x + 3x {}^{2} + 8 + 5x {}^{2} + 5 } \\ \end{gathered}$

$\begin{gathered}\\ \large\dashrightarrow\mathsf {5x + 8x {}^{2} + 8 + 5 } \\ \end{gathered}$

$\begin{gathered}\\ \large\dashrightarrow\mathsf {5x + 8x {}^{2} + 13 } \\ \end{gathered}$

$\begin{gathered}\\ \large\dashrightarrow \orange{ \underline{ \boxed{\mathsf {8x {}^{2} + 5x + 13} }}}\\ \end{gathered}$
