The correct option for the synthetic division is A. 2x³ + 3x² + 9x + 7

<h3>How to solve the division?</h3>

Write down the first coefficient without changes and multiply the entry in the left part of the table by the last entry in the result.

Then, add the obtained result to the next coefficient of the dividend, and write the sum. All the coefficients are the coefficients of the quotient, and the last coefficient is the remainder.

Rewrite the function f(x)=3(x+1)^2-2 in the form f(x)=ax^2+bx+c
frutty [35]

Answer:

f(x) = 3x² + 6x + 1

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Expand by FOIL (First Outside Inside Last)
  • Standard Form: f(x) = ax² + bx + c
  • Vertex Form: f(x) = a(bx + c)² + d

Step-by-step explanation:

<u>Step 1: Define function</u>

f(x) = 3(x + 1)² - 2

<u>Step 2: Find Standard Form</u>

  1. Expand by FOILing:                        f(x) = 3(x² + 2x + 1) - 2
  2. Distribute 3:                                     f(x) = 3x² + 6x + 3 - 2
  3. Combine like terms (constants):    f(x) = 3x² + 6x + 1
