The solution to the problem 2x2 is 4 (the result of multiplication).
It means that you increase something's height by x2 and its width by x2 (and depth by x2 when you have a 3D object)
It depends on the capability of your computer. In this web site, there are the text controls right above where I am typing my answer. I will type r2, then select the '2' by itself, then click the x2 above the text box. Those two symbols, x2 and x2 are for subscript and superscript. So, when done, r-squared is correctly displayed like this: r2.
Each element is the mean of the corresponding elements. Thus, the mean of (x1, y1) and ( x2, y2) is [( x1 + x2)/2, (y1 + y2)/2]
If you mean: x2+3x+2 then it is (x+1)(x+2) when factored
If you mean using subscript (for example H2SO4) on WikiAnswers - Type your text as normal, then go back and highlight the text you want to change, and press the button on the blue line above - that's labelled X2

If you mean x2 + 2x + 15: Then the answer would be that it's a quadratic expression with no factors. If you mean x2 - 2x + 15: Then it can be factored out to: (x - 5)(x + 3) If you mean x2 + 2x - 15: Then it can be factored out to: (x + 5)(x - 3)
The answer to this depends on what you mean by "x 7" If you mean: x2 -7x, then it can be factored out as x(x - 7) If you mean: x2 - x7, then you can factor it out as: x2(1 - x5) If you mean: x2 - x + 7, then it can not be factored If you mean: (x2 - x)7, then the inner term can be factored, giving you (x[x - 1])7 If you mean something else, then you will need to be more clear with your question.
If you mean y = x2, then yes, it is nonlinear.

do you mean, x2 = n?? Take the square root.
