An inequality of the form
|X| < k,
where X is an expression in x, and k is a non-negative number, is solved by solving the following inequality
-k < X - k
You are given
|s| <= 2
Follow the pattern above to get
-2 <= s <= 2
In interval notation, the answer is
[-2, 2]
Answer: 2a^-4 * b^2
Step-by-step explanation:
The answer is C. I'm pretty sure of it.
Answer:
x = -1, x = 1
Step-by-step explanation:
Factor the equation. (It's a difference of squares, so we know the form will be (a-b)(a+b).)

Test this by FOILing it out, if you're unsure. This is something it can be good to memorize!
Set it equal to 0.

Separate the two parenthetical expressions by the Zero Product Property.

Solve for x!
