If the point representing the number x on the number axis is to the left of the origin, the result of simplifying 2A + radical a ^ 2 is?

If the point representing the number x on the number axis is to the left of the origin, the result of simplifying 2A + radical a ^ 2 is?

The point representing the number a is to the left of the origin, a

The point on the number axis representing the number a is on the left side of the origin, which simplifies the square of | a-radical a|

If the point of a is to the left of the origin, then a

If the root sign (1-x) squared = 3, then x=___ Given that the point on the number axis representing the number a is on the left side of the origin, then | 2A + root sign a squared|=___

Root sign (1-x) square = 3
（1-x)²=9
1-x=±3
x1=-2, x2=4
|2A + root a square|
=│2a+│a││
=│2a-a│
=│a│
=-a

If the distance between the corresponding points of two numbers with equal absolute bits on the number axis is 6, then the two numbers are___ ．

∵|3 | = | - 3 |, 3 | 3 = 6, the distance between the corresponding points of two numbers with equal absolute bits on the number axis is 6, the two numbers are 3 and - 3 respectively, so the answer is: 3 and - 3
