Here \(x^2 - 2x = 0\)
or x (x - 2) = 0
either x = 0 or x-2 =0 or x = 2
If x = 0 then Statement 1 < Statement 2
If x= 2 then Statement 1 = Statement 2
Hence option D

Explanation
Factorize \(x^2 - 2x = 0\):
\(x^2 - 2x = 0\)
\(x(x - 2) = 0\)
\(x = 0\) OR \((x - 2) = 0\)
x = 0 or 2.
Thus, Quantity A could be less than or equal to Quantity B. The relationship cannot be determined from the information given.
(Note that you cannot simply divide both sides of the original equation by x. It is illegal to divide by a variable unless it is certain that the variable does not equal zero.)
Factorize \(x^2 - 2x = 0\):
\(x^2 - 2x = 0\)
\(x(x - 2) = 0\)
\(x = 0\) OR \((x - 2) = 0\)
x = 0 or 2.
