'2x' is already two things multiplied together: 2*x. Be sure to learn the parts of a polynomial. The number out front is called the coefficient, it's just a constant that is multiplied by the rest of everything else. The next is the letter, or variable, and has meaning when used in a function, but otherwise is not much more than to keep polynomials seperate. The last is the exponent.
Don't let all the letters of algebra confuse you, the follow the same rules as anything else. When you multiply a constant by itself, it is just something^2. Just like constants, variables without an exponent have an implied exponent of "1" (something^1 = theSameThing). Multiplying by itself raises the power by 1.
[remember x = x^1]:
x*x = x^2
x^2*x = x^3
2x*x = 2*x*x = 2*(x*x) = 2*(x^2) = 2x^2

+425 Extremely easy question. 12 year olds can solve it in like 1 second.
Not a good birthday treat.
+425 If you can't solve it, you are only a 4th grader. I think you are 10...
