एक दृश्य ग्रिड \(x^2-xy-6y^2\) बनाता है। कौन-सी भुजाएं सही हैं?
A visual grid forms \(x^2-xy-6y^2\). Which sides are correct?
Explanation opens after your attempt
D. (x+2y) और (x-3y)signed sides
Concept
Here (2y+(-3y)=-y) and (2y\cdot(-3y)=-6y-2). In exams add negative tiles carefully.
Why this answer is correct
The correct answer is D. (x+2y) और (x-3y) / signed sides. Here (2y+(-3y)=-y) and (2y\cdot(-3y)=-6y-2). In exams add negative tiles carefully.
Exam Tip
(2y+(-3y)=-y) और (2y\cdot(-3y)=-6y-2) है। परीक्षा में ऋणात्मक टाइलों का योग सावधानी से करें।
