$4$ $4$

$x = 2$ $x = 2$ , so you substitute the $x$ $x$ in the equation for $2$ $2$
When you replace all of the $x$ $x$ variables with 2, you get:

$2 {(2)}^{2} - 2$ $2(2)^2 - 2$
Simplify and get;
$2 (4) - 2$ $2(4)-2$

Then your final answer is:
$4$ $4$

If x=2x = 2, what is the value of 2x2−x2x^2-x?
