To find the coefficient of x in the division of the polynomial expression, we first need to clarify the operation. It appears that you are interested in dividing the polynomial expression 18x3 by the polynomial 12x2 + 3x + 6x2.
1. **Combine like terms** in the denominator:
- 12x2 and 6x2 combine to give 18x2.
- So the denominator becomes: 18x2 + 3x.
2. **Rewrite the expression** you seek to evaluate:
We are looking at:
3. **Dividing 18x3 by 18x2** gives:
- This simplifies to:
- 18x3 / 18x2 = x.
4. **Now, we must break down the remaining** 3x in the denominator to see how it interacts with x:
Continuing the polynomial long division:
- The result of dividing 18x3} by 18x2} gives us x, as above.
- Now, you multiply x by the entire denominator:
So next, we take:
- x * (18x2 + 3x) = 18x3 + 3x2.
5. **Subtracting this from the original numerator gives:**
- Original numerator: 18x3
- Minus the product: (18x3 + 3x2)
- Result: -3x2.
6. This process continues, however, since we are mainly focused on the coefficient of x from our division, we find:
Initially from the division we found:
Coefficient of x = 1
Thus, the coefficient of x in the entire operation is simply 1.
