1 answer

To multiply the polynomials \( (3x - 1)(2x + 4) \), we can use the distributive property (also known as the FOIL method for binomials):

  1. Multiply the first terms: \( 3x \cdot 2x = 6x^2 \)
  2. Multiply the outer terms: \( 3x \cdot 4 = 12x \)
  3. Multiply the inner terms: \( -1 \cdot 2x = -2x \)
  4. Multiply the last terms: \( -1 \cdot 4 = -4 \)

Now, we combine all these results:

\[ 6x^2 + 12x - 2x - 4 \]

Combining like terms gives:

\[ 6x^2 + (12x - 2x) - 4 = 6x^2 + 10x - 4 \]

So the completed polynomial is:

\[ 6x^2 + 10x - 4 \]

Filling in the blanks for your question:

_x^2 + _x + _

is:

6 (for the x^2 coefficient), 10 (for the x coefficient), and -4 (the constant term).

Thus, the answer is:

6, 10, -4
