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
A. (A=B)
Concept
Since (x-2-5x+6=(x-2)(x-3)), the solutions are (2,3). Make the roots the elements of the set.
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.
Exam Tip
(x-2-5x+6=(x-2)(x-3)) इसलिए हल (2,3) हैं। समीकरण के हलों को समुच्चय के अवयव बनाएं।
