Answer

The result of dividing \(6x^{3}+17x^{2}+20x+18\) by \(2x+3\) is \(3x^{2}+4x+4+\frac{6}{2x+3}\).

Solution

Calculate or simplify the expression \( (6x^3+17x^2+20x+18)/(2x+3) \). Divide the polynomials by following steps: - step0: Using Long Division to Divide Polynomials: \(\frac{\left(6x^{3}+17x^{2}+20x+18\right)}{\left(2x+3\right)}\) - step1: Calculate: \(3x^{2}+4x+4+\frac{6}{2x+3}\) The result of dividing \(6x^{3}+17x^{2}+20x+18\) by \(2x+3\) is \(3x^{2}+4x+4+\frac{6}{2x+3}\).

To divide the polynomial \( 6x^3 + 17x^2 + 20x + 18 \) by \( 2x + 3 \), we can use polynomial long division. 1. Divide the leading term of the numerator \( 6x^3 \) by the leading term of the denominator \( 2x \) to get \( 3x^2 \). 2. Multiply \( 3x^2 \) by \( 2x + 3 \) to get \( 6x^3 + 9x^2 \). 3. Subtract \( (6x^3 + 9x^2) \) from \( (6x^3 + 17x^2 + 20x + 18) \). The new polynomial becomes \( 8x^2 + 20x + 18 \). 4. Now, repeat the process: divide \( 8x^2 \) by \( 2x \) to get \( 4x \). 5. Multiply \( 4x \) by \( 2x + 3 \) to get \( 8x^2 + 12x \). 6. Subtract \( (8x^2 + 12x) \) from \( (8x^2 + 20x + 18) \) to get \( 8x + 18 \). 7. Divide \( 8x \) by \( 2x \) to get \( 4 \). 8. Multiply \( 4 \) by \( 2x + 3 \) to get \( 8x + 12 \). 9. Finally, subtract \( (8x + 12) \) from \( (8x + 18) \) to get \( 6 \). Putting it all together, the quotient is \( 3x^2 + 4x + 4 \) and the remainder is \( 6 \). Therefore, \[ \frac{6x^3 + 17x^2 + 20x + 18}{2x + 3} = 3x^2 + 4x + 4 + \frac{6}{2x + 3} \]
