How do you write the product as a trinomial (3x + 2)(2x - 3)(3x+2)(2x3)?

Multiply each term in one expression times each term in the other, then simplify by combining like terms.

Explanation:

There are other possible descriptions. Here is one of them:

To write the product (3x + 2)(2x - 3)(3x+2)(2x3) in another form, we need to multiply each terms in 3x+23x+2 times each term in 2x-32x3.
(In algebra, 'terms' are things that are added together.)

So we need to multiply 3x3x times 2x2x and times -33 (don't forget the minus sign!)
he we will multiply 22 times 2x2x and times -33 (again with the minus sign)

So here's how we can write that:

(3x + 2)(2x - 3) = 3x(2x)+3x(-3) +2(2x)+2(-3)(3x+2)(2x3)=3x(2x)+3x(3)+2(2x)+2(3)

= 6x^2-9x+4x-6=6x29x+4x6

Now I see two terms involving xx, so we'll combine them into a single term:

= 6x^2-5x-6=6x25x6

Notice, now that we're finished, that the answer turns out to be a trinomial.

The instructions included the word 'trinomial' to try to make it clear that they didn't want us to rewrite the product in some other way -- like by changing the order, or by not combining like terms or doing some other way of rewriting.
