यदि \(A={x:x\in \mathbb{N}, x^2-5x+6=0}\) है तो कौन सा समुच्चय (A) के बराबर है?
If \(A={x:x\in \mathbb{N}, x^2-5x+6=0}\) then which set is equal to (A)?
Explanation opens after your attempt
A. ({2,3})
Concept
(x-2-5x+6=(x-2)(x-3)), so the solutions are (2,3). First solve the equation and then write the set.
Why this answer is correct
The correct answer is A. ({2,3}). (x-2-5x+6=(x-2)(x-3)), so the solutions are (2,3). First solve the equation and then write the set.
Exam Tip
(x-2-5x+6=(x-2)(x-3)) है इसलिए हल (2,3) हैं। पहले समीकरण हल करें फिर समुच्चय लिखें।
