Yogita Ingle 4 years, 3 months ago

Expanding along R₁
x(x²−12)−3(2x−14)+7(12−7x)=0
⇒x³−12x−6x+42+84−49x=0
⇒x³−67x+126=0 ………………i
Here 126×1=9×2×7126×1=9×2×7
For x=2, 2³−67×2+126=134−134=0
Hence x=2 is a root.
For x=7,6³−67×7+126=469−169=0
Hence x=7 is also a root.

Jerry Singh 4 years, 3 months ago

For every a in Z, We have (a-a) which is divisible by 5 So, (a, a) is in R Hence, R is reflexive Let (a, b) be in R then (a-b) =5k(say) And, - (a-b) is also divisible by 5 Hence,( b-a) is divisible by 5 Therefore, (b, a) is in R whenever (a, b) is in R So, R is symmetric Let (a,b) and (b,c) be in R. Then, (a-b) is divisible by 5, also (b-c) is divisible by 5. Now, (a-b) +(b-c) =(a-c) is also divisible by 5. Hence,(a,c) is in R whenever (a, b) and (b, c) is in R. So, R is transitive Since, R is reflexive, symmetric and Transitive Thus, R is an equivalence relation.

Closure property

Posted by Mayank Agarwal 4 years, 3 months ago

CBSE > Class 12 > Mathematics

1 answers

Meghna Thapar 4 years, 3 months ago

The closure property means that a set is closed for some mathematical operation. That is, a set is closed with respect to that operation if the operation can always be completed with elements in the set. Thus, a set either has or lacks closure with respect to a given operation. A set is closed under an operation if performance of that operation on members of the set always produces a member of that set. For example, the positive integers are closed under addition, but not under subtraction: is not a positive integer even though both 1 and 2 are positive integers.

Determinant

Every square matrix A is associated with a number, called its determinant and it is denoted by det (A) or |A| .

Only square matrices have determinants. The matrices which are not square do not have determinants

ANSWER

Let * defined on the set {1, 2, 3, 4, 5} by a*b=L.C.M of a and b. Is * a binary operation? Justify your answer.

Gaurav Seth 4 years, 3 months ago

Consider the composition table :

LCM	1	2	3	4	5
1	1	2	3	4	5
2	2	2	6	4	10
3	3	5	3	12	15
4	4	4	12	4	20
5	5	10	15	20	5

In the given composition table, all the elements are not in the set {1, 2, 3, 4, 5}.

If we consider a = 2 and b = 3, a * b = LCM of a and b = 6 ∉ {1, 2, 3, 4, 5}.

Thus, * is not a binary operation on {1, 2, 3, 4, 5}.
