we have b-a
take - sign common,we get
yes -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.
Negative B was created in 2001.
You can't prove a negative with direct evidence.
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.
If you have B- blood:You can give to people with: B+, B-, AB+, and AB-.You can recieve blood from people with: B- and O-.
