Answer:

$5(x+2)(x-2)$

Step-by-step explanation:

Find the greatest common factor (GCF) of the 2 terms:

GCF is 5.

Factor out the GCF:

$5x^2-20\\5(\frac{5x^2}{5} -\frac{20}{5} )\\5(x^2-4)$

Rewrite as a difference of squares ( $a^2-b^2=(a+b)(a-b)$ ):

$5(x^2-2^2)\\5(x+2)(x-2)$

Given that x is an integer, what is the solution of <br>|x-1|<img src="https://tex.z-dn.net/?f=%20%5Cleqslant%201" id="TexFormul

Varvara68 [4.7K]

Answer:

see explanation

Step-by-step explanation:

Inequalities of the type | x | ≤ a always have solutions of the form

- a ≤ x ≤ a

Given

| x - 1 | ≤ 1 then

- 1 ≤ x - 1 ≤ 1 ( add 1 to each of the 3 intervals )

0 ≤ x ≤ 2

Since we require an integer solution then x = 0, 1, 2
