If (x+y+z) is a factor of (x^3+y^3+z^3-3xyz), what is the other factor?(x^3+y^3+z^3-3xyz) में यदि (x+y+z) गुणनखंड है, तो दूसरा गुणनखंड क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( x^2+y^2+z^2-xy-yz-zx )( 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.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।
