Question

What is the difference between x2 and 2x

Answer 1

x2 is the same as x*x
2x is the same as x * 2

If we use 3 as an example:
3=x

x2 = 3*3 = 9
2x = 2*3 = 6

Answer 2

Answer:

x2 and 2x are two different mathematical expressions.

x2 is read as "x squared" and represents the square of the variable x. It means that we multiply x by itself. For example, if x = 3, then x2 = 32 = 9.
2x is read as "two times x" and represents twice the value of the variable x. It means that we multiply x by 2. For example, if x = 3, then 2x = 2(3) = 6.
So, the main difference between x2 and 2x is that the first expression involves squaring the variable x, while the second expression involves multiplying x by a constant (the number 2).
