Hard Mathematics Sets Class 11 Level 7

यदि \(A={x:x\) \(x^2-5x+6=0\) का हल है(}) और \(B=\{2,3\}\) हैं तो क्या सत्य है?

If \(A={x:x\) is a solution of \(x^2-5x+6=0\)(}) and \(B=\{2,3\}\), what is true?

Explanation opens after your attempt
Correct Answer

A. (A=B)

Step 1

Concept

Since (x-2-5x+6=(x-2)(x-3)), the solutions are (2,3). Make the roots the elements of the set.

Step 2

Why this answer is correct

The correct answer is A. (A=B). Since (x-2-5x+6=(x-2)(x-3)), the solutions are (2,3). Make the roots the elements of the set.

Step 3

Exam Tip

(x-2-5x+6=(x-2)(x-3)) इसलिए हल (2,3) हैं। समीकरण के हलों को समुच्चय के अवयव बनाएं।
