1. The problem is to expand and simplify the function $f(x) = (x^3 - 2x)(x^5 + 6x^2)$.
2. We use the distributive property (also called FOIL for binomials) to multiply each term in the first polynomial by each term in the second polynomial:
$$f(x) = x^3 \cdot x^5 + x^3 \cdot 6x^2 - 2x \cdot x^5 - 2x \cdot 6x^2$$
3. Multiply the powers of $x$ by adding exponents:
- $x^3 \cdot x^5 = x^{3+5} = x^8$
- $x^3 \cdot 6x^2 = 6x^{3+2} = 6x^5$
- $-2x \cdot x^5 = -2x^{1+5} = -2x^6$
- $-2x \cdot 6x^2 = -12x^{1+2} = -12x^3$
4. Write the expanded expression:
$$f(x) = x^8 + 6x^5 - 2x^6 - 12x^3$$
5. Rearrange terms in descending order of powers:
$$f(x) = x^8 - 2x^6 + 6x^5 - 12x^3$$
6. This is the simplified expanded form of the function.
Final answer:
$$\boxed{f(x) = x^8 - 2x^6 + 6x^5 - 12x^3}$$
