एक दृश्य मॉडल \(x^2-y^2\) को पुनर्व्यवस्थित करके (x-y) ऊंचाई वाला आयत बनाता है। उसकी लंबाई क्या होगी?
A visual model rearranges \(x^2-y^2\) into a rectangle of height (x-y). What will be its length?
Explanation opens after your attempt
Correct Answer
B. (x+y)sum side
Concept
(x-2-y-2=(x-y)(x+y)), so if the height is (x-y), the length is (x+y). In exams identify the other side of the rearranged rectangle.
Why this answer is correct
The correct answer is B. (x+y) / sum side. (x-2-y-2=(x-y)(x+y)), so if the height is (x-y), the length is (x+y). In exams identify the other side of the rearranged rectangle.
Exam Tip
(x-2-y-2=(x-y)(x+y)), इसलिए ऊंचाई (x-y) हो तो लंबाई (x+y) है। परीक्षा में पुनर्व्यवस्थित आयत की दूसरी भुजा पहचानें।
