\begin{tabular}{l} Simplify. \\ \( -3 c^{2}-2 c^{2} \) \\ Combining like terms: Integer coefficients \\ \hline Explanation \\ Check \end{tabular}

When you combine the like terms \(-3c^2\) and \(-2c^2\), you simply add their coefficients together. So, \(-3 - 2 = -5\). Therefore, the expression simplifies to \(-5c^2\). Always remember, when combining like terms, focus on the coefficients and keep the common variable and its exponent the same. Simple as pie! Just think of it as putting together similar puzzle pieces to form a clearer picture.
