To divide \( 6x^3 - 11x^2 - 27x + 10 \) by \( 3x - 1 \) using long division, follow these steps: 1. **Divide the Leading Terms**: Divide the leading term of the dividend \( 6x^3 \) by the leading term of the divisor \( 3x \): \[ \frac{6x^3}{3x} = 2x^2 \] 2. **Multiply and Subtract**: Multiply \( 2x^2 \) by the entire divisor \( 3x - 1 \): \[ 2x^2(3x - 1) = 6x^3 - 2x^2 \] Now subtract this from the original polynomial: \[ (6x^3 - 11x^2) - (6x^3 - 2x^2) = -11x^2 + 2x^2 = -9x^2 \] Now bring down the next term \( -27x \) to get \( -9x^2 - 27x \). 3. **Divide Again**: Now divide \( -9x^2 \) by \( 3x \): \[ \frac{-9x^2}{3x} = -3x \] 4. **Multiply and Subtract**: Multiply \( -3x \) by \( 3x - 1 \): \[ -3x(3x - 1) = -9x^2 + 3x \] Subtract this from \( -9x^2 - 27x \): \[ (-9x^2 - 27x) - (-9x^2 + 3x) = -27x - 3x = -30x \] Bring down the \( +10 \) to get \( -30x + 10 \). 5. **Divide Again**: Now divide \( -30x \) by \( 3x \): \[ \frac{-30x}{3x} = -10 \] 6. **Multiply and Subtract**: Multiply \( -10 \) by \( 3x - 1 \): \[ -10(3x - 1) = -30x + 10 \] Subtract this from \( -30x + 10 \): \[ (-30x + 10) - (-30x + 10) = 0 \] The result of the long division is: \[ 2x^2 - 3x - 10 \] Since the remainder is \( 0 \), the division is exact. Thus, we have: \[ \frac{6x^3 - 11x^2 - 27x + 10}{3x - 1} = 2x^2 - 3x - 10 \]
