What does negative b squared equal to?
It's equal to positive b squared, or (b x b) .
Is it possible for a to be a negative number in the equation a squared equal b explain why or why not?
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'.
Is a negative number minus a negative number equal to a positive number?
Take any a, b < 0. Is it true a - b > 0? No. For example: let a = -10000000000000 and b = -1, a - b = -10000000000000 + 1 = -9999999999999 < 0.
Why is a negative number squared equal to a positive square?
By definition (-1)*(-1)=1.(-a)*(-b)(-1)*(a)*(-1)*(b)(-1)*(-1)*(a)*(b)(a)*(b) ■
Does a positive number plus negative number equal positive or negative?
This depends on what the numbers are. For example,6 + (-4) = 6 - 4 = 2 which is a positive numberOR5 + (-8) = 5 - 8 = -3 which is a negative numberIn general, if you are adding a positive number a to a negative number b,if a is less than b, the result will be negative.if a is greater than b, the result will be positive.
What does negative b squared equal to?
It's equal to positive b squared, or (b x b) .
Does a negative subtracted from a negative equals in a negative in algebra?
It can. Negative 2 minus negative 1 = negative 1. However, it sometimes might be positive. Negative 5 minus negative 16 = positive 11. If you have two equal negative variables, such as -a - -a, you will get -2a. -2a may still be positive though, if a is a negative number. An example of having two unequal negative numbers is -a - -b, which is -a + b. That may be positive or negative depending on what a and b are equal to.

What does 10 to the negative 1 equal?
10-1 = 1/10 A number raised to a negative power is equal to the reciprocal of the number raised to the power. So a-b = (1/a)b = 1/ab
Is a negative number minus a negative number equal to a positive number?
Take any a, b < 0. Is it true a - b > 0? No. For example: let a = -10000000000000 and b = -1, a - b = -10000000000000 + 1 = -9999999999999 < 0.
For real numbers a and b when is the equation a plus b equals a-b true?
a + b = a - bSubtract a from each side:+ b = - bThe only way that 'b' can equal its own negative is if b=0.So (a + b) can equal (a - b) only if b=0.(It doesn't matter what 'a' is.)
Why is a negative number squared equal to a positive square?
By definition (-1)*(-1)=1.(-a)*(-b)(-1)*(a)*(-1)*(b)(-1)*(-1)*(a)*(b)(a)*(b) ■

Why does Negative times a negative equal a positive?
There are a lot of long examples that help to visualize why a negative times a negative is a positive, but this is just going to be an algebraic proof. Let x = a*b + (-a)*b + (-a)*(-b) If we factor out the (-a) for the second part of the equation, we are left with: x = a*b + (-a)*(b+(-b)) b+(-b) = 0, so the resulting equation is: x = a*b + (-a)*0 Any number times zero is zero, so: x = a*b Next, we go back to the original equation, and factor our the "b" from the first part, leaving: x = (a+(-a))*b + (-a)*(-b) a+(-a) = 0, so: x = 0*b + (-a)*(-b) 0*b = 0, so: x = (-a)*(-b) Now we see that x equals both a*b and (-a)*(-b), meaning: a*b = (-a)*(-b) So the product of 2 negative numbers must be equal the the product of their positive counterparts, i.e., a positive result.
What does b equal in 2b minus b minus 10 equals negative 13?
Taking it step by step: 2b - b - 10 = -13 b - 10 = -13 b = -13 + 10 b = - 3
