if we have set A and B

consider A={1,2,3,4}and B={3,4,5,6}

the union of these sets is A and B={1,2,3,4,5,6}and

the intersection is{3,4}

the union and the intersection are same only if A=B

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

No, because the intersection of two equivalent sets will have a union the same size as its intersection.

What is union and intersection of set?

Union: putting the elements of the sets together Intersection: getting the common elements of the sets Example: Set A={1,2,3} Set B={2,3,4,5} Union of Sets A&B= {1,2,3,4,5} Intersection of Sets A&B = {2,3}

What is the union intersection set?

Given two or more sets there is a set which is their union and a set which is there intersection. But, there is no such thing as a "union intersection set", as required for the answer to the question.

Why empty set is a set?

The concept of closure: If A and B are sets the intersection of sets is a set. Then if the intersection of two sets is a set and that set could be empty but still a set. The same for union, a set A union set Null is a set by closure,and is the set A.

Difference between Union and Set Intersection Operation?

union means to group the given sets. where as intersection means to pick out the common elements from the given sets. if set a has 1,2,3 elements and B has 1,2,3,4,5. then its union will have 1,2,3,4,5 as its elements. and its intersection will have 1,2,3 as its elements.
