Question

use the foil method to find the product. (7x^5-4)(x^8-2)

Answer 1

what is the foil method?

Answer 2

i dont remember

Answer 3

first terms
outter terms
inner terms
last terms
multiply those together then combine like terms and you have your answer.

Answer 4

its rather ironic that foil is a memory device that you cant remember :)

Answer 5

gt was right :)

Answer 6

FOIL is a ridiculous memory based method to teach "distributive" property of factors.

Answer 7

(a+b)(c+d) = ac + ad + bc + bd
according to FOIL.

Answer 8

i know when im doing a problem like that im always saying first outer inner last while im doing the problem lol

Answer 9

FOIL focuses on the "order". It is mathematically WRONG to focus on the order of the terms. Order does not matter - mathematically speaking.

Answer 10

i just multiply them together like they taught me back in teh 2nd grade or so

Answer 11

(7x^5-4)(x^8-2) = 7x^5 * x^8 - 2*7*x^5 - 4*x^8 + 4*2 = 7x^13 - 14x^5 - 4x^8 + 8

Answer 12

thats what i got to thank you

Answer 13

what answer did you get?

Answer 14

Another thing that annoys me a lot is the "soh cah toa" in trigonometry. It drives me bananas.

Answer 17

its algibra

Answer 18
