+To determine the complexity of the given expression, we need to analyze the number of operations it performs.
+
+The expression is: $5n + 10n^2 = O(n^2)$
+
+In this expression, there are two terms: $5n$ and $10n^2$. The term with the highest power of $n$ dominates the complexity, which in this case is $10n^2$.
+
+Since the highest power of $n$ is $n^2$, the complexity of the expression is $O(n^2)$.
+
+Therefore, the statement is **true**.
