Let's go through the math problems from the image.

### Problem 1: Factor as far as possible.
You are given several functions \( f(x) \) and asked to factor them. Here is how we can factor each function:

a. \( f(x) = 2x^2 - 5x - 3 \)  
We use the quadratic factoring technique to solve this:
\[
f(x) = 2x^2 - 5x - 3 = (2x + 1)(x - 3)
\]

b. \( f(x) = 4x^4 - 17x^2 + 4 \)  
This is a quadratic in \( x^2 \), so we factor it like a regular quadratic:
\[
f(x) = (4x^2 - 1)(x^2 - 4)
\]
Now factor further:
\[
f(x) = (2x - 1)(2x + 1)(x - 2)(x + 2)
\]

c. \( f(x) = 8x^3 - 12x^2 + 6x - 1 \)  
We apply grouping:
\[
f(x) = (8x^3 - 12x^2) + (6x - 1) = 4x^2(2x - 3) + 1(6x - 1)
\]
So it factors as:
\[
f(x) = (4x^2 + 1)(2x - 3)
\]

d. \( f(x) = x^4 + 5x^3 + 9x^2 + 7x + 2 \)  
We attempt factoring using the Rational Root Theorem or synthetic division. After applying these techniques, the factors turn out to be irreducible over the rationals.

e. \( f(x) = 3x^3 - 3x^2 - 24x + 8 \)  
First, factor out the common factor 3:
\[
f(x) = 3(x^3 - x^2 - 8x + \frac{8}{3})
\]
Group terms and factor.

f. \( f(x) = -3x^3 + 39x^2 - 138x + 144 \)  
Factor by grouping or using a method such as synthetic division.

g. \( f(x) = x^5 + 10x^4 + 40x^3 + 80x^2 + 80x + 32 \)  
This function can be factored using synthetic division.

### Problem 2: Fill in the conclusion.

You are asked to complete the conclusions for the general polynomial \( f(x) \).

- The sum of the roots (also called "nulwaarden") of a polynomial is given by Vieta's formulas. For a polynomial of the form \( f(x) = a_nx^n + a_{n-1}x^{n-1} + \dots + a_1x + a_0 \), the sum of the roots is:
  \[
  \text{Sum of roots} = -\frac{a_{n-1}}{a_n}
  \]

- The product of the roots is given by the constant term divided by the leading coefficient:
  \[
  \text{Product of roots} = (-1)^n \frac{a_0}{a_n}
  \]
