The "x2" designation on a lens typically indicates that the lens provides a 2x magnification, meaning that objects will appear twice as large in the frame compared to viewing them with the naked eye. This designation is often found on telephoto or zoom lenses, where the ability to magnify distant subjects is essential. In some contexts, "x2" can also refer to a teleconverter, which is an accessory that increases the effective focal length of a lens by a factor of two.
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.
set.
The solution to the problem 2x2 is 4 (the result of multiplication).
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.
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)

What do you mean? It is a DSLR camera, not a lens.
