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)
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
Assuming you mean: (9x × x2)2 Then we can say: = (9x3)2 = 81x6
It's used to increase the focal length of a lens. There are two types you can get a x1.4 and x2. If you place the x2 between the camera and a 300mm lens, then you end up with a 600mm lens - but it will cost you 2 stops of exposure, so the autofocus may well stop working.

Depends on your microscope. We've got one that's a 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.

What do you mean? It is a DSLR camera, not a lens.
do you mean, x2 = n?? Take the square root.
