What is a Zero product postulate?
ab = 0 if and only if (a = 0 or b = 0)
How do you solve a squared plus a plus ab plus b equals 0?
That factors to (a + 1)(a + b) a = -1, -b b = -a
What does ab equals 1a plus 1B plus ab equal to?
ab=1a+1b a is equal to either 0 or two, and b is equal to a
Does A plus B equals AB?
No, A+B is left as A+B AB would be A x B
What is a value of a b if a equals 10 and b equals -5?

If a equals 0 0 and b equals 6 3 find ab if necessary submit your answer as a decimal to the nearest tenth remember ab means the distance between points a and b?
6.7
A3 - b3 equals?
0
What would you suggest when A crossB equals 0 and AB equals 0?
Assuming that cross means 'divide' B is equal to 0
What is a Zero product postulate?
ab = 0 if and only if (a = 0 or b = 0)
A plus B equals AB?
No. A times B = AB
How do you solve a squared plus a plus ab plus b equals 0?
That factors to (a + 1)(a + b) a = -1, -b b = -a
What does ab equals 1a plus 1B plus ab equal to?
ab=1a+1b a is equal to either 0 or two, and b is equal to a
If you know that AB plus B equals C what is the conclusion?
C minus B equals AB
Does A plus B equals AB?
No, A+B is left as A+B AB would be A x B
What is a value of a b if a equals 10 and b equals -5?

Why is a negative times a negative a positive?
Here is a proof. Let a and b be any two real numbers. Consider the number x defined as x = ab + (-a)(b) + (-a)(-b). We can write this out differently as x = ab + (-a)[ (b) + (-b) ] Then, by factoring out -a , we find that x= ab + (-a)(0) = ab + 0 = ab. Also, x = [ a + (-a) ]b + (-a)(-b) And by factoring out b, we find that x=0 * b + (-a)(-b) = 0 + (-a)(-b) = (-a)(-b). Therefore x = ab and x = (-a)(-b) Then, by the transitivity of equality, we have ab = (-a)(-b).
How to solve this 8.333333 equals ab b to power of negative 1 1.8 equals ab b to power of 2?
8 1/3 = ab^-1, 1.8 =ab^2
