Answer 1

Hello there!

Simplify the product using FOIL. (4x + 3)(2x + 5)

 
Your answer is: 8x^2 + 26x + 15
-----------------------------------------------------------------------------------------------------

Explanation/Work:

So, what is FOIL?

FOIL:

First

Outside

Inside

Last


First: 4x * 2x = 8x^2

Outside: 4x * 5 = 20x

Inside: 3 * 2x = 6x

Last: 3 * 5 = 15

This is: 8x^2 + 20x + 6x + 15

Now, let's simplify this

20x + 6x = 26x

Our final answer is: 8x^2 + 26x + 15


I hope I helped!

Answer 2

8x^2+20x+6x+15. Combine like terms. 8x^2+26x+15. When using foil just multiply the contents of one pair of brackets on another pair.
