The Deep Dive
Let's combine like terms in the expression \( -12x^{2} + 5x - 3x^{2} + 9 \). First, we gather the \(x^{2}\) terms: \(-12x^{2} - 3x^{2} = -15x^{2}\). Next, the \(x\) term is simply \(5x\) since there are no other \(x\) terms. Lastly, the constant terms add up to \(9\). Putting it all together, the simplified expression is \( -15x^{2} + 5x + 9 \).
