यदि एक क्षेत्र मॉडल \(36x^2-1\) दिखाता है, तो अंतर के वर्गों से कौन सा आयत बनेगा?
If an area model shows \(36x^2-1\), which rectangle will be formed by difference of squares?
Explanation opens after your attempt
A. ((6x+1)(6x-1))
Concept
Since (36x-2=(6x)2) and \(1=1^2\), the dimensions are (6x+1) and (6x-1). Exam tip: identify the sides of both squares.
Why this answer is correct
The correct answer is A. ((6x+1)(6x-1)). Since (36x-2=(6x)2) and \(1=1^2\), the dimensions are (6x+1) and (6x-1). Exam tip: identify the sides of both squares.
Exam Tip
(36x-2=(6x)2) और \(1=1^2\), इसलिए आयाम (6x+1) और (6x-1) होंगे। परीक्षा में दोनों वर्गों की भुजाएं पहचानें।
