What is the factored form of the expression?
s4 – 16
a. (s - 2)2(s + 2)2
b. (s - 2)(s + 2)
c. (s - i)(s + i)(s - 2)(s + 2)
d. (s^2 + 4)(s + 2)(s - 2)

(s + 2) (s -2).

Step-by-step explanation:

Given  : .

To find : What is the factored form of the expression.

Solution : We have given that  .

By .

=

We can write   as

= (s + 2) (s -2).

Then ,

 =  (s + 2) (s -2).

Therefore,    (s + 2) (s -2).

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

first one is a: renaming a fraction. second one is c: de-c
