Technically neither. A more mathematically accurate way to word it would be "Is this true for all real numbers x?"
True man .
The square of a positive fraction will be less than the original number.
This is my favourite explanation as it is the most succinct. However, you must say "The square of any positive fraction less than one..." I know what you meant, but fractions can be greater than one (e.g. 4/3). A better wording would be: The square of any positive fraction less than one will be less than the fraction itself.
x 2 ≥ x is false for all the Real Numbers x such that 0 < x < 1 and true for all other Real Numbers.
thanks Sir
Its only true if x is greater than 1
Or less than 0.
if x is 0.5 the x2 is 0.25 so x2 is smaller than x
It is not true for all real numbers less than 1
Nope, the statement is true for all real values less than or equal to 0 . It is only false for real numbers 0 < x < 1
0 and 1 squared do not increase
Wrong, the condition states that x 2 is greater than or equal to x . For 0 and 1, x 2 is equal to x .

Yes...you are correct...in this 2 cases the statement is correct...
If x is defined as a quotient then the numbers' squared product will be less than the number itself. The only definition for x that will make the proposition true is when x is greater than or equal to 1 or less than or equal to 0. Since x^2 must be greater than or equal to x.
Very obvious. 1/2 * 1/2 is 1/4.
x^2 is not always greater than or equal to x... It is true only when x=0 or x is any real number greater than or equal to 1. But when 0<x<1, the statement is false. For example, if x=0.5, then x^2=(0.5)^2=0.25 which is less than 0.5
x^2>or=x divide both sides by x.
x>1
above step is not true for all real numbers.
therefore original statement is false
x^2 isn't always >x
.5^2 = .25, and .25 is less than .5
The statement is false for
0<x<1
Hence the answer is false
Given, x^2≥x Or, x^2-x≥0 Or, x(x-1) ≥0 Now,This implies that x ϵ (-∞,0]U[1,∞),i.e,for real numbers between 0 and 1 will not satisfy the given inequality. Thus the answer will be false.
x^2-x>=0 then derivation, solution of derivation, then three intervals (-infinite; 0) [0;1/2] (1/2;infinite)
Or you could do x=1
(1)^2=1
If 0<x<1, then x^2 is actually smaller than x. So it is not true for ALL real numbers x.
It's true if x>1 or if -1>x>0.
It will be smaller when X is a fraction number
Only when x is a positive fraction. Negative fractions, indeed any negative number, is less than its square as the square will be positive.

Yea ... only false with positive fractions. Other than that it is true.

INDIRECT PROOF
x^2 < x
x^2 - x < 0
x(x-1)<0
0<x<1
so, the statement is FALSE when 0<x<1
