एक दृश्य मॉडल \(9a^2+24a+16\) को पूर्ण वर्ग दिखाता है। उसकी भुजा कौन-सी होगी?
A visual model shows \(9a^2+24a+16\) as a perfect square. What will its side be?
Explanation opens after your attempt
Correct Answer
A. (3a+4)correct side
Concept
(9a-2=(3a)2), \(16=4^2\), and \(2\cdot3a\cdot4=24a\). In exams the side is made from the roots of the two squares.
Why this answer is correct
The correct answer is A. (3a+4) / correct side. (9a-2=(3a)2), \(16=4^2\), and \(2\cdot3a\cdot4=24a\). In exams the side is made from the roots of the two squares.
Exam Tip
(9a-2=(3a)2), \(16=4^2\), और \(2\cdot3a\cdot4=24a\) है। परीक्षा में दोनों वर्गों की जड़ से भुजा बनती है।
