−3u−2(9u−2)

Answer 1

To simplify the expression \(-3u - 2(9u - 2)\), follow these steps:

1. Distribute the \(-2\) in the expression: \[ -2(9u - 2) = -2 \cdot 9u + -2 \cdot (-2) = -18u + 4 \]

2. Replace the original expression with the result of the distribution: \[ -3u - 18u + 4 \]

3. Combine like terms \(-3u\) and \(-18u\): \[ -3u - 18u = -21u \]

4. Therefore, the simplified expression is: \[ -21u + 4 \]

So, the final simplified form of the expression \(-3u - 2(9u - 2)\) is: \[ -21u + 4 \]
