Multiply the polynomials (3x−1)(2x+4).

3 answers

To multiply the polynomials (3x - 1)(2x + 4), we use the distributive property:

(3x - 1)(2x + 4) = 3x(2x) + 3x(4) - 1(2x) - 1(4)

Simplifying each term:

= 6x^2 + 12x - 2x - 4

Combining like terms:

= 6x^2 + 10x - 4

So, the product of the polynomials (3x - 1)(2x + 4) is 6x^2 + 10x - 4.
