Question

(у-4) (3x+5y-2) How do I multiply the following expression?
​

Answer 1

Answer:

$3xy + 5y^{2} - 12x - 22y + 8$

Step-by-step explanation:

You will use the FOIL method, which is very similar to the distributive property.

In order to do multiply correctly, multiply the y by 3x, 5y, and -2. You should get:

$3xy + 5y^{2} - 2y$

Then multiply the -4 by 3x, 5y, and -2 where you should get:

$- 12x - 20y + 8$

By using the foil method, you got rid of the parentheses. Now you can simply combine like terms and get your final answer:

$3xy + 5y^{2} - 12x - 22y + 8$

I hope this helps you!
