|2+B| is a non-negative number because the absolute value cannot be negative.

The square of (3a+2c) is also non-negative, because the squares are all non-negative.

And the square of |2+b|+(3a+2c) =0.

They are 0 respectively.

The smallest positive integer is 1.

So b=-2 a= 1 c=3/2.

Then go on like this, and finally it is equal to -38/2 1.
