Answer 2

yes you can always simplify the factor to check your work
(2x + 3) (x + 7)
use FOIL
Fronts 2x * x = 2x^2
Outers 2x * 7 = 14x
Inners 3 * x = 3x
Lasts 7 * 3 = 21
then add everything 2x^2 + 14x + 3x + 21
combine like terms
2x^2 + 17x + 21
we can conlude that (2x + 3) (x + 7) is the factored form of 2x^2 + 17x + 21

Answer 3

uhhhhhhh Foil? i was never taught this mark.

Answer 4

well you dont have to use foil but its just used to make sure you dont forget some of the products

Answer 5

ooooooooooh. OKay.

Answer 6

First Outer Inner Last
(F+I)(O+L)

Just an example
