Question

simplify using the product FOIL (5x-5)(2x-4)

Answer 1

(5x - 5)(2x - 4)
FOIL
10x^2 + 20x - 10x + 20
10x^2 - 10x + 20
factor..
10(x^2 - x + 2)

Answer 2

Do you know what the FOIL method is?

Answer 3

oops made a mistake...
10x^2 + 20x - 10x + 20
10x^2 + 10x + 20
factor
10(x^2 + x + 2)

Answer 4

Ok Thank You! got all understood all of my other questions on my assingment exect for this one. Thanks for clearing it up a bit!

Answer 5

Do I need to explain what I did ?

Answer 6

Answer 7

It will be no problem for me to explain it

Answer 8

ok

Answer 9

FOIL stands for First, Outside, Inside, Last
(5x - 5)(2x - 4)
now you multiply the first terms in each set..
5x * 2x = 10x^2
now you multiply the outside terms...
5x * -4 = - 20x
now you multiply the inside terms..
-5 * 2x = -10x
now you take the last terms...
-5 * -4 = 20
Now put it all together...
10x^2 - 20x - 10x + 20 (combine like terms)
10x^2 - 30x + 20 (I made a mistake again on the previous answers...this one is correct)
now we can factor..
10(x^2 - 3x + 2) <-- answer

I am sorry about the mistakes on the previous answers. Go with this one.
Do you have any questions ?

Answer 10
