To use long division to divide \((2x^3 + 7x^2 + 2x + 9) \div (2x + 3)\), follow these steps:1. **Divide the leading term of the dividend by the leading term of the divisor:**
Write
above the division line.2. **Multiply the entire divisor by this result and subtract from the dividend:**
Subtract this from the original dividend:
3. **Repeat the process with the new polynomial:** Divide the leading term of the new polynomial by the leading term of the divisor:
Write
above the division line next to
.4. **Multiply the entire divisor by this result and subtract from the new polynomial:**
Subtract this from the current polynomial:
5. **Continue the process:** Divide the leading term of the remaining polynomial by the leading term of the divisor:
Write
above the division line next to
and
.6. **Multiply the entire divisor by this result and subtract from the remaining polynomial:**
Subtract this from the current polynomial:
The quotient is
and the remainder is
. Therefore, the final answer is:
