यदि \(A={x:x\in \mathbb{Z}, x^2=9}\) और \(B=\{-3,3\}\) हैं तो सही कथन कौन सा है?
If \(A={x:x\in \mathbb{Z}, x^2=9}\) and \(B=\{-3,3\}\) then which statement is correct?
Explanation opens after your attempt
A. (A=B)
Concept
The integer solutions of \(x^2=9\) are (-3) and (3). Check the negative solution in square equations too.
Why this answer is correct
The correct answer is A. (A=B). The integer solutions of \(x^2=9\) are (-3) and (3). Check the negative solution in square equations too.
Exam Tip
\(x^2=9\) के पूर्णांक हल (-3) और (3) हैं। वर्ग वाले समीकरण में ऋणात्मक हल भी जांचें।
