If the absolute value of a minus 1 = 1 minus a, then the value range of a is

If A-1 = 1-A, then the value range of a is a ≤ 1

If the absolute value of a is equal to negative a, what is the value range of a

Negative infinity to zero

Let X and y be the two real roots of the equation m2-2am + A + 6 = 0, then the minimum value of (x-1) 2 + (Y-1) 2 is ()
A. -1214B. 18C. 8D. 34

Then (x-1) 2 + (Y-1) 2 = x2 + y2-2 (x + y) + 2 = (x + y) 2-2xy-2 (x + y) + 2 = (2a) 2-2 (a + 6) - 4A + 2 = 4a2-6a-10 = 4 (a-34) 2-494
