Answer 2

To simplify the given expression $-0.1x(2x^2 + 6)(5 - 4x^2)$, we'll follow these steps:

1. Distribute $-0.1x$ across the terms inside the parentheses.
2. Simplify each term inside the parentheses.
3. Combine like terms.

Let's go through these steps:

Step 1: Distribute $-0.1x$ across the terms inside the parentheses: $= -0.1x \times 2x^2 - 0.1x \times 6 + 0.1x \times 2x^2 + 0.1x \times 6x^2$

Step 2: Simplify each term inside the parentheses: $= -0.2x^3 - 0.6x + 0.2x^3 + 0.6x^3$

Step 3: Combine like terms: $= (-0.2x^3 + 0.2x^3 + 0.6x^3) - 0.6x$ $= 0.6x^3 - 0.6x$

So, the simplified expression is $0.6x^3 - 0.6x$.
