The product of a rational number and its opposite must be?
The product of a rational number and its opposite must be non - normal.
The product of a rational number and its opposite must be non - positive.
We know that a is the smallest positive integer, b and c are rational numbers, and the square of |2+b (3a+2c)=0 is the value of -a^2+c^2+4/4ab+c!
An absolute value plus a square number is 0, indicating that both parts are 0.
So b=-2,3a=-2c
The minimum positive integer is 1, so a=1, c=-1.5
-A^2+c^2+4=-1+2.25+4=5.25
4Ab+c=-8-1.5=-9.5
A^2+c^2+4/4ab+c=-19/11
