If the question is x^2 + x^2 then the answer is definitely 2x^2.
The exponent doesn't change, just the base. Think of it this way, one apple plus one apple is ...yes, two apples. It's the same with x and other variables.

1 2 Plus 1 2 Equal What

This makes no sense, you do not need to add anything to complete the square. You could complete the square if this was quadratic but it is only a linear expression.

x squared is written on a computer as x^2
x^2 + x^2 = 2x^2

x^2 + x^2
= 2x^2

if it is 2x + 2x then its 4x
if its 1x2+1x2 then its 4
if its x^2 +x^2 then its 2x^2

x^2 + x^2 = 2x^2
See it like this:
1x^2 + 1x^2 = 2x^2
add the coefficients. 1 + 1 = 2
easy, isn't it? ðŸ˜€

if you mean x^squared + x^squared it is 2x^squared
if you mean 2x+2x (written like that in the text book with the 2 out front) then its 4x

2x^2
