Answer:

No, let me explain

Step-by-step explanation:

The definition of squared is a value multiplied by itself, and in this case, 2x(x) x is being multiplied by itself.  Keep in mind that x is a value, so it could be any number.  We can't say that x times 2x equals 2x, because you are multiplying 2x by the value of x.
