Question

Write the product as a trinomial.

(x + 2)(x + 4)



x2 + 8x + 8



x2 + 8x + 6



x2 + 6



x2 + 6x + 8

Answer 1

D, x² + 6x + 8

Explanation:

to write (x + 2)(x + 4) as a trinomial, we can use FOIL to expand the equation, which stands for:

First terms

Outside terms

Inside terms

Last terms

i have higlighted the terms i am multiplying in bold to follow the steps easier

F: (x + 2)(x + 4)

x²

O: (x + 2)(x + 4)

4x

I: (x + 2)(x + 4)

2x

L: (x + 2)(x + 4)

8

we have the following equation:

x² + 4x + 2x + 8 < combine like terms

x² + 6x + 8 is our trinomial, so that is answer choice D
