When limx approaches 0, can (e ^ x-1-x) / x ^ 2 be equal to LIM (e ^ x-1) / x ^ 2-lim (x / x ^ 2) according to the four mixed operations of limit

No, the premise of the four algorithms is that the two limits of addition or subtraction must exist, and the two limits here are infinite, that is, the limit does not exist, so it cannot be used
