  • 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.

  • 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? 😀

  • 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
