Final answer:
To divide the polynomial 4x^3 + 6x + 18 by x + 2, use long or synthetic division, dividing each term separately and following the appropriate steps for each method.
Step-by-step explanation:
The division of the polynomial 4x^3 + 6x + 18 by x + 2 can be carried out using long division or synthetic division. In long division, you divide the first term of the numerator by the first term of the denominator (4x^3/x) and multiply the result by the entire divisor, subtract that product from the numerator, and continue the process with the resulting polynomial until you reach a remainder or a term that can no longer be divided by x+2. Synthetic division is a shortcut where you use coefficients and a special set of steps to simplify the process.
The division of exponentials rule is also relevant here; where you divide the coefficients and subtract the exponents when the bases are the same. In this case, there are no like bases, so this rule does not apply directly. Instead, we divide each term separately by the linear divisor.
