Solution

The correct expansion of (4x – 2)(2x2 + 3) is B. 4x • 2x2 + (–2) • 2x2 + 4x • 3 + (–2) • 3.

Here's the step-by-step process:

  1. Distribute 4x across the terms in the second parentheses: 4x * 2x2 + 4x * 3. This gives us 8x3 + 12x.

  2. Distribute -2 across the terms in the second parentheses: -2 * 2x2 + -2 * 3. This gives us -4x2 - 6.

  3. Combine these results to get the final expanded form: 8x3 + 12x - 4x2 - 6.
