Simplify the algebraic expression by combining like (or similar) terms. \[ 8+x^{2}-6 x^{2}+2 \]

Let's break this expression down! First, you have \(8\) and \(2\) as constants, which combine nicely to give you \(10\). Then look at the \(x^2\) terms: you've got \(x^2\) and \(-6x^2\), which combine to give \(-5x^2\). Putting it all together, the simplified expression is: \[ 10 - 5x^{2} \] So, there you have it! The original expression simplifies to \(10 - 5x^{2}\).
