यदि \(x^2+4x+4\) को वर्गाकार टाइलों से बनाया जाए, तो बाहरी भुजा क्या होगी?
If \(x^2+4x+4\) is made using square tiles, what will be the outer side?
Explanation opens after your attempt
B. (x+2)
Concept
Since \(4=2^2\) and the middle term is (4x), the side is (x+2). Exam tip: check the square root of the last term.
Why this answer is correct
The correct answer is B. (x+2). Since \(4=2^2\) and the middle term is (4x), the side is (x+2). Exam tip: check the square root of the last term.
Exam Tip
\(4=2^2\) और बीच का पद (4x) है इसलिए भुजा (x+2) है। परीक्षा में अंतिम पद का वर्गमूल देखें।
