एक आयत मॉडल में (x+2) और (x+5) की जगह (x+3) और (x+4) रख दिए गए। दोनों क्षेत्रों में क्या अंतर है?
In a rectangle model, (x+2) and (x+5) are replaced by (x+3) and (x+4). What is the difference between the two areas?
Explanation opens after your attempt
A. (1)
Concept
The first area is \(x^2+7x+10\) and the second is \(x^2+7x+12\). In exams, when linear terms match, compare constants.
Why this answer is correct
The correct answer is A. (1). The first area is \(x^2+7x+10\) and the second is \(x^2+7x+12\). In exams, when linear terms match, compare constants.
Exam Tip
पहला क्षेत्र \(x^2+7x+10\) और दूसरा \(x^2+7x+12\) है। परीक्षा में समान रैखिक पद होने पर स्थिर अंतर देखें।
