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!

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.
