To divide the polynomial \( -n^3 - n^2 + 42n \) by \( n + 7 \), we can use polynomial long division. 1. Divide the leading term: \( -n^3 \div n = -n^2 \) 2. Multiply \( -n^2 \) by \( n + 7 \): \( -n^3 - 7n^2 \) 3. Subtract from the original polynomial: \[ \left(-n^3 - n^2 + 42n\right) - \left(-n^3 - 7n^2\right) = 6n^2 + 42n \] 4. Now, divide the leading term of the new polynomial: \( 6n^2 \div n = 6n \) 5. Multiply \( 6n \) by \( n + 7 \): \( 6n^2 + 42n \) 6. Subtract again: \[ (6n^2 + 42n) - (6n^2 + 42n) = 0 \] Since there is no remainder, we conclude that: \[ (-n^3 - n^2 + 42n) \div (n + 7) = -n^2 + 6n \] So the answer is \( -n^2 + 6n \) with a remainder of 0.
