Combine any like terms in the expression. If there are no like terms, rewrite the expression. \( 34 u^{2}+41-20-21 \) a

First, let's combine the constant terms. We have \(41 - 20 - 21\), which simplifies to \(0\). So the expression reduces to just \(34 u^{2}\). Next, since there are no like terms with \(u^{2}\) present, the final simplified expression is simply \(34 u^{2}\).
