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.

B negative or O negative.
If the mother is A negative, and the father is B positive, they could have children who are A negative, A positive, B negative, B positive, AB negative, AB positive, O negative, or O positive.
yes
Negative B was created in 2001.
Evidence such as the distribution of fossils, rock formations, and magnetic fields on different continents support the theory of continental drift and the breakup of Pangaea. The matching geological features, such as mountain ranges and coastlines, on opposite sides of the Atlantic Ocean provide further evidence that the continents were once connected. Additionally, the movement of tectonic plates and the ongoing process of plate tectonics help explain the separation of the continents from Pangaea.
Since you cannot prove a negative statement, one cannot prove that ghosts do not exist.
It is impossible to prove a negative. You shouldn't even bother to try.
Blood type B negative is compatible with receiving red blood cells from individuals with blood types B negative and O negative.
