Write the product as a trinomial.
(x + 3)(x + 4)

x² + 7x + 12

Step-by-step explanation:

You are given two different binomials. Use FOIL to multiply, because product means to multiply.

First:

x · x = x²

Outside:

x · 4 = 4x

Inside:

3 · x = 3x

Last:

3 · 4 = 12

Now, add all these terms together to get this:

x² + 4x + 3x + 12

Combine like terms (add the terms with x's):

x² + 7x + 12

And you're done!

*This is a trinomial because there are three terms.
