Question

What is the factored form of the expression?

s4 – 16

Answer 1

What is each number divisible by?

Answer 2

The greatest common factor?

Answer 3

i'm not sure

Answer 4

Ok what numbers give you 16. Example 16*1, etc..

Answer 5

You there?

Answer 6

i think you just factor it out, idk i'm really confused

Answer 7

ok first you have to find the greatest common factor for both 4 and 16. 16/4 is 4 and 4/4 is 1. You with me so far?

Answer 8

yes

Answer 9

Ok so the GCF is 4 now if we divide everything by 4 we get (s-4). You get that step?

Answer 10

remember that it is understood that a variable that is by itself like x is the same as 1x. We just dont put it because its understood.

Answer 11

well i ended up getting (s - 2)2(s + 2)2 but it ended up being wrong

Answer 12

yes that is wrong. Your answer would be 4(s-4). Why? Because 4*s - (4 * 4) = 4s-16

Answer 13

You see what I did?

Answer 14

noooo u.u

Answer 15

Actually what kind of factoring are you doing?

Answer 16

Answer 19
