$a^3 - b^3$ फॅक्टरायझ करचें.

A$(a-b)(a^2 - ab + b^2)$
B$(a-b)(a^2 + 2ab + b^2)$
C$(a-b)(a^2 + ab + b^2)$
D$(a-b)^3$
Answer & Solution
Correct answer: C. $(a-b)(a^2 + ab + b^2)$
घनांचो फरक वळख $a^3-b^3=(a-b)(a^2+ab+b^2)$ आसा. अशे तरेन पर्याय C बरोबर आसा. पर्याय A $ab$ चेर चुकीचें चिन्न आसा, आनी पर्याय B चेर $ab$ चेर चुकीचो गुणांक $2$ आसा.
