यदि \(E={x:x\in Z,\ x^2-5x+6=0}\), तो (E) क्या है?
If \(E={x:x\in Z,\ x^2-5x+6=0}\), what is (E)?
Explanation opens after your attempt
A. \(E=\{2,3\}\)
Concept
\(x^2-5x+6=0\) can be written as ((x-2)(x-3)=0).
Why this answer is correct
So (x=2) or (x=3), hence \(E=\{2,3\}\).
Exam Tip
In a set defined by a quadratic condition, the solutions become the elements. चरण 1: \(x^2-5x+6=0\) को ((x-2)(x-3)=0) लिखा जा सकता है। चरण 2: इसलिए (x=2) या (x=3), अतः \(E=\{2,3\}\)। चरण 3: द्विघात शर्त वाले समुच्चय में हल ही अवयव बनते हैं।
