Let's assume we have two sets
First set is A
second set is B
we know that
Union of two sets is the set that contains elements or objects that belong to either A or to B or to both.
So, it does not leave any element from any set
So, for union of two sets to become null , sets A and B won't have any element
For example:
set A={ }
set B= { x : for all real value of x ,x^2 +1=0 }
Since, set B won't have any elements
so,
A∪B=Ф
Yes, the union of two sets have a solution of a null set........Answer

Answer:
Step-by-step explanation:
2x² + 9x = -7
2x² + 9x + 7 = 0
When we multiply we should get 2*7 = 14 and when we add we should get 9. Find the factors of 14 ---> 1,2,7,14. Factors are 2,7 as when we multiply we get 14 and we we add, get 9
2x² + 2x + 7x + 7 = 0
2x( x + 1) + 7 (x + 1) = 0
(x + 1)(2x + 7) = 0
Answer:
Step-by-step explanation:
a ÷ a%
(a)a ÷ (a/100)(a)
a ÷ a2/100
a(100/a2)
100 / a
