Question

Find the product:

(x-y) (3x-4y)

Answer 1

FOIL it out

Answer 2

How do I FOIL

Answer 3

First Outside Inside Last - FOIL
Take your first number (in this case variable) in the first term and multiple it by the first number in the second term

Answer 4

so its 3x-4y ?

Answer 5

Remember when we multiply 3x * x that's saying 3x*1x

Answer 6

When we multiply 3*1 we get 3 but when we multiply 3x*x we get 3x^2

Answer 7

\[3x ^{2}\]

Answer 8

because you have 2 x's ? so it makes it 3x^2

Answer 9

Yes

Answer 10

then the outters which are x and -4y

Answer 11

how would I do those?

Answer 12

Then the two "middle" terms -y and 3x

Answer 13

Remember that if x is alone it always has a 1 in front of it. So x is the same thing as 1x

Answer 14

SO x*-4y=? (Take a shot at it)
