\(x^3+y^3+z^3-3xyz\) में यदि (x+y+z) गुणनखंड है, तो दूसरा गुणनखंड क्या होगा?
If (x+y+z) is a factor of \(x^3+y^3+z^3-3xyz\), what is the other factor?
Explanation opens after your attempt
A. \( x^2+y^2+z^2-xy-yz-zx \)
Concept
This is the identity (x-3+y-3+z-3-3xyz=(x+y+z)\(x^2+y^2+z^2-xy-yz-zx\)). Exam tip: remember the three-variable cubic identity.
Why this answer is correct
The correct answer is A. \( x^2+y^2+z^2-xy-yz-zx \). This is the identity (x-3+y-3+z-3-3xyz=(x+y+z)\(x^2+y^2+z^2-xy-yz-zx\)). Exam tip: remember the three-variable cubic identity.
Exam Tip
यह प्रसिद्ध पहचान (x-3+y-3+z-3-3xyz=(x+y+z)\(x^2+y^2+z^2-xy-yz-zx\)) है। परीक्षा में तीन चर वाली घन पहचान याद रखें।
