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