Question

Choose the correct simplification of the expression (−2x + 8y)(9x − 3y).

−18x^2 + 78xy − 24y^2

18x^2 + 78xy − 24y^2

−18x^2 − 78xy + 24y^2

−18x^2 + 72xy − 24y^2

Answer 1

Use FOIL

Answer 2

I understand its foil but ive tried to solve it and don't get the right answer

Answer 3

What is F: -2x(9x) ?

Answer 4

yes -18

Answer 5

(-2x)(9x)=-18x^2

Answer 6

okay so next is -2x(-3y)

Answer 7

-2x(-3y)= 6xy

Answer 8

yes

Answer 9

then is it -2x(8y)?

Answer 10

No. After Outer, do Inner which is (8y)(9x)

Answer 11

72xy then one more which is -2x(8y)?

Answer 12

or no 8y(-3y)

Answer 13

equals -24^2 so is D

Answer 14

yes. (8y)(-3y)

Answer 15

can you help me with one more?
