  14. (-2x^5 + x^4 - x^3 + 2x^2 - 1; x^3 + x^2 + 1)

in exercises 15-20, write each polynomial in the form (p(x) = d(x)q(x) + r(x)). you may use synthetic division wherever applicable.

  1. (x^2 + x + 1; d(x) = x + 1)
  2. (x^2 + x + 1; d(x) = x - 1)
  3. (3x^3 + 2x - 8; d(x) = x - 4)
  4. (4x^3 - x + 4; d(x) = x - 2)
  5. (x^6 - 3x^5 + x^4 - 2x^2 - 5x + 6; d(x) = x^2 + 2)
  6. (-x^6 + 4x^5 - x^3 + x^2 + x - 8; d(x) = x^2 + 4)

in exercises 21-28, use synthetic division to find the function values.

  1. (f(x) = x^3 - 7x + 5); find (f(3)) and (f(5)).

  5. (f(x) = x^5 - 2x^3 + 12); find (f(3)) and (f(-2)).
  6. (f(x) = -2x^5 + x^4 + x^2 - 2); find (f(-3)) and (f(4)).

ight)).

in exercises 29-38, determine whether (q(x)) is a factor of (p(x)) and justify your answer.

  1. (p(x) = x^3 - 7x + 6; q(x) = x - 3)
  2. (p(x) = x^3 - 5x^2 + 8x - 4; q(x) = x + 2)

  4. (p(x) = x^3 - 5x^2 + 8x - 4; q(x) = x - 2)

Explanation:

Identify the scope of the request

The user has provided an image containing a large set of exercises (Exercises 1–38) on polynomial division, synthetic division, the Remainder Theorem, and the Factor Theorem. Since the user did not specify a single problem, we will solve the very first representative problem, Exercise 1, to demonstrate the method clearly.

Exercise 1: Find the quotient and remainder when the first polynomial is divided by the second:

$$(2x^2 + 13x + 15) \div (x + 5)$$

Set up synthetic division

Using the Synthetic Division knowledge point, we set up the division.
The divisor is \(x + 5\), so the test value is \(c = -5\).
The coefficients of the dividend \(2x^2 + 13x + 15\) are \(2\), \(13\), and \(15\).

Perform synthetic division calculations

Using the Synthetic Division knowledge point:

  1. Bring down the leading coefficient: \(2\).
  2. Multiply by \(-5\): \(-10\). Add to \(13\): \(13 + (-10) = 3\).
  3. Multiply by \(-5\): \(-15\). Add to \(15\): \(15 + (-15) = 0\).

The resulting coefficients are \(2\) and \(3\), with a remainder of \(0\).

Interpret the results

The quotient is \(2x + 3\) and the remainder is \(0\).

Answer:

For Exercise 1:
Quotient: \(2x + 3\)
Remainder: \(0\)
