What number has a negative absolute value Why is it non-positive? For example, the absolute value of -10 is also 10! What number has a negative absolute value Why is it non-positive? For example, the absolute value of -10 is 10!

The absolute value of a number is positive, so no number has a negative absolute value.

Given that a is the smallest positive integer, b and c are rational numbers and |2+b (3a+2c)2=0, find the algebraic formula 4ab+c −A2+c+4.

From the known a=1,
Because |2+b (3a+2c)2=0,
So 2+b=0,3a+2c=0,
So b=-2, c=−3

Set a=1, b=-2, c=−3
