Question

simplify.
$-4c^2 - 5c^2$

Explanation:

Step1: Identify like terms

The terms \(-4c^2\) and \(-5c^2\) are like terms (same variable part \(c^2\)).

Step2: Combine coefficients

To combine them, add their coefficients: \(-4 - 5 = -9\).
So, \(-4c^2 - 5c^2 = (-4 - 5)c^2 = -9c^2\).

Answer:

\(-9c^2\)
