If you are adding variables, say x + 2x, would you also add the variables, to make it squared instead of just another x?

No.......this used to confuse me, too....

 

The power [exponent] on the variables remains the same.....thus

 

1x + 2x   = 3x

 

It's when we are multiplying that the powers change.....thus

 

1x * 2x   =  [1 *2] * [x * x ]   = 2x^2

 

 

cool cool cool
