we have b-a
take - sign common,we get
-(-b+a)=-(a-b)
hence proved

∙ 10y agoyes -a=-b means you multiplied each side by -1 which is allowed
Of course it is. 'a' can be any positive or negative number, and 'b' is its square.That's no problem.What is difficult is for 'b' to be a negative number in the same equation.No real number for 'a' can produce a negative 'b'.
Negative times negative equals positve, so -a*-b=ab (positive ab)
No, they are not because fractions can be negative also. fractions aren't integers
-5/4 + b ≤ -16 b ≤ -16 + 5/4 b ≤ -59/4
Prove to whom? You can't "prove" a negative.
you can't, but you can't prove a negative either.
We don't. It is impossible to prove a negative. It is called the Paradox of negative information. You can only prove something does exist, you cannot prove non-existence.
