What is formula of a b )( ab?
The formula for a2- b2 is (a+b)(a-b)= a2- b2. It is called the difference of squares formula.
What is a B )( AB called?
It is used as a formula in mathematics. Hence, it is called an algebraic identity.
What is a B equal to?
The equality between A and B is written A = B, and pronounced A equals B. … Two objects that are not equal are said to be distinct. For example: means that x and y denote the same object.
What is a plus BA minus B?
Answer: a plus b a minus b equal to a square minus b square. arrenhasyd and 13 more users found this answer helpful. Thanks 11.
How do you solve AB sets?
Formally we can write: A-B = {x| x A but x B}. (Remember, out loud we would say, “the set of all x’s such that x is an element of A but x is NOT an element of B.” Notice that the complement of A, A’ is the same thing as U-A.
What is AB in algebra?
ab means a × b. a. 2. means a × a.
Is A B C the same as a BC?
(A/B)/C is equal to A/(BC) because you are still dividing a by b and c. For example (20/5)/2 is equal to 2 while 20/(5*2) is also equal to 2. This is because of the order of operations.
What is X A XB?
(x-a)(x-b) is equal to x^2-xb-ax-ab= x^2 -x(b+a) –ab or = x^2 -b(x+a) –ax.
What is AB in math?
A-B is the set of all elements that are in A but NOT in B, and B-A is the set of all elements that are in B but NOT in A. Notice that A-B is always a subset of A and B-A is always a subset of B.
How do you find AB when given A and B?
ab = b – a ie direction from a to b. and ba = a – b ie direction from b to a.
When is a-(ANB) =A-B?
- This is possible only when B is a proper subset of A. Thus, A– (AnB)=A-B only when B is a proper subset of A (or, B=A which is a special condition of B being proper subset of A) What is the definition of A – B ?
What is the value of a + B(A – B)?
- (a + b) (a − b) = a 2 − b 2 It is read as the a plus b times a minus b is equal to the a squared minus b squared.
How do you use the (A + B)(A – B) rule?
- So, we can use the formula for simplifying given algebraic expression. Take a = 3 p and b = 4 q and substitute them in the a + b times a − b formula. Thus, we use the ( a + b) ( a − b) special binomial product rule in mathematics.
