Answer
La expresión simplificada es \( -4x^{2}+3x+2 \).
Solution
Calculate or simplify the expression \( \frac{1}{2}(12x^{2}+2)-10x^{2}+3x+1 \).
Simplify the expression by following steps:
- step0: Solution:
\(\frac{1}{2}\left(12x^{2}+2\right)-10x^{2}+3x+1\)
- step1: Multiply the terms:
\(6x^{2}+1-10x^{2}+3x+1\)
- step2: Subtract the terms:
\(-4x^{2}+2+3x\)
La expresión simplificada es \( -4x^{2}+2+3x \).

To simplify the expression \( \frac{1}{2}\left(12 x^{2}+2\right)-\left(10 x^{2}-3 x-1\right) \), start by distributing the \( \frac{1}{2} \): \[ \frac{1}{2} \cdot 12x^2 + \frac{1}{2} \cdot 2 = 6x^2 + 1. \] Now, rewrite the full expression: \[ 6x^2 + 1 - (10x^2 - 3x - 1). \] Distributing the negative sign gives us: \[ 6x^2 + 1 - 10x^2 + 3x + 1. \] Now, combine like terms: - For \( x^2 \): \( 6x^2 - 10x^2 = -4x^2 \), - For \( x \): \( 3x \), - For constants: \( 1 + 1 = 2 \). Putting it all together, the simplified expression is: \[ -4x^2 + 3x + 2. \] So the final answer is: \[ -4x^2 + 3x + 2. \]
