For any value of $X$, is $X+X$ equal to $X \times X$?
For any value of $X$, is $X+X$ equal to $X \times X$?
This Question has 1 answers.
We need to determine if the equation:
$X + X = X \times X$
$2X = X^2$
Rearrange the equation:
$X^2 - 2X = 0$
Factorize:
$X(X - 2) = 0$
Setting each factor to zero:
$X = 0$ or $X = 2$
The equation $X + X = X \times X$ is **not** true for all values of $X$, but it holds for:
$X = 0$ or $X = 2$
$X + X = X \times X$
$2X = X^2$
Rearrange the equation:
$X^2 - 2X = 0$
Factorize:
$X(X - 2) = 0$

$X = 0$ or $X = 2$
The equation $X + X = X \times X$ is **not** true for all values of $X$, but it holds for:
$X = 0$ or $X = 2$
