Answer:
the second one
Step-by-step explanation:
Answer: that the variable can be any number.
Step-by-step explanation:
So we have a linear equation and we end with a relation of the way:
x = x
an example can be if we have:
2*x + 4 = 2*(x + 2)
if you solve that, you will end with a relationship x = x
this means that any value of x will made that equality true.
so x can be any number.
A quadrilateral MUST be a parallelogram if it has one pair of opposite sides both parallel and congruent. A quadrilateral MUST be a parallelogram if it has both pairs of its opposite angles congruent (or equal in measure). A quadrilateral MUST be a parallelogram if it has both diagonals bisecting each other.

Answer:
= x(x+1)(x-1)
Step-by-step explanation:
Given the expression x³ - x
On factorizing
x³ - x
= x(x²-1)
Using difference of two square
a² - b² = (a+b) (a-b)
x² - 1
= x² - 1²
= (x+1)(x-1)
The complete factor
x³ - x
= x(x²-1)
= x(x+1)(x-1)
