I assume you mean an identity property. The identity property of addition states a number plus 0 gives you that original number. Eg. 1+0=1 The identity property of multiplication states a number times 1 gives you that original number. Eg. 1*1=1
Only the number two, as any number added to itself is equal to the number x 2. Technically the number 0 would also qualify, as 0 x 2 = 0 and 0+0=0
A negative plus a negative still gives a negative answer.
3x2 + 17x + c = 0, rearranging gives c = -3x2 - 17x
No answer in integers. Quadratic formula gives roots as -1.268 and -4.732

14 plus 4 gives us positive 18, while 0 minus 3 gives us negative three.
The sum of 2 plus 0 plus 0 plus 0 plus 0 plus 0 plus 0 plus 0 plus 0 plus 0 plus 0 plus 0 plus 0 plus 0 plus 0 plus 0 equals 2.
Additive inverse of a number a is that number which on addition with a gives 0.7 is additive inverse of -7.The property shown is additive inverse property because the addition yields 0.

A negative plus a negative still gives a negative answer.
The answer is 0. 0 divided by any non-zero number gives the answer 0. Division by 0 is not defined.
3x2 + 17x + c = 0, rearranging gives c = -3x2 - 17x
The solution to 40 plus 40 times 0 plus 1 is 41. The number name is forty-one.

Yes, that's what we mean by "-y" or "negative y" -- it's the additive inverse of y. -y is defined as the number which, when added to y, gives zero. y + -y = 0 (Zero, in turn, is defined as the additive identity -- the number which, when added to x, gives x.)
